About

"Mech Builder" is a relaxing puzzle game inspired by model building, where you can cut out, assemble, paint, and customize 50+ model kits with complete freedom. Unlock kitbash mode to create your own models and time trial to challenge yourself against the clock. With carefully crafted models and pieces, building takes around 7-9 hours, while time trial takes 2-3 hours. This game offers endless repeatability and creativity in building mechs, waifus, armors, figures, and more.

  • The game is a relaxing and enjoyable experience, perfect for unwinding after a long day.
  • It effectively scratches the itch for building model kits without the expense and mess of real-life Gunpla.
  • The sound effects and satisfying mechanics of assembling models create a calming atmosphere.
  • A significant number of models feature low-resolution textures and AI-generated assets, which detracts from the overall quality.
  • The painting and decal mechanics are limited and do not save customizations, making them feel less impactful.
  • The developer has been criticized for a lack of transparency regarding the use of AI in the game's assets.
  • gameplay
    30 mentions Positive Neutral Negative

    The gameplay is described as a relaxing and mindless experience, suitable for background activity, with a satisfying core mechanic of constructing kits. However, it suffers from a lack of depth, repetitive mechanics, and numerous bugs, alongside criticism of the developer's honesty and design choices. While some players find enjoyment in the puzzle aspects, others are frustrated by the simplistic painting mechanics and poorly designed parts.

    • “Relaxing gameplay, a cheaper way to fuel my Gunpla habits, what more can a guy ask for?”
    • “Very relaxed gameplay, perfect to wind down after a hectic day.”
    • “Amazing gameplay, so very exhilarating, would make all mechs again.”
    • “The gameplay loop itself was pretty mindless, something to do in the background while listening to a video or podcast.”
    • “Assets generated by AI, one single boring audio track, assembly mechanics that feel empty and weightless compared to Last Call BBS, a combative and dishonest developer, and many, many bugs made this an annoying slog.”
    • “The difficulty doesn't ramp up, new mechanics are not introduced, new concepts are not explored.”
  • graphics
    20 mentions Positive Neutral Negative

    The graphics of the game feature nicely detailed artwork, but the reliance on AI-generated designs has led to mixed feelings among players, particularly regarding the inconsistency in mech aesthetics and the limitations in kit-bashing. While some appreciate the overall look, many express disappointment over the lack of original artistry and the challenges posed by differing styles among the mechs. Overall, a more cohesive art style and better scaling options for parts could enhance the visual experience.

    • “The artwork is nicely detailed, and while you can only paint the parts a single color, you can still achieve a decent look overall.”
    • “A way to scale parts in kitbash mode would be nice, enabling those giant helmets to get some parts usage. Otherwise, more models in a consistent art style would be the best for it.”
    • “Honestly, I don't care that it's AI artwork; it's still a fun and relaxing game, and it's the best purchase I've made in a while.”
    • “The game's mechs certainly aren't designed with kit-bashing in mind at all, either, which would make a lot more sense if they really are traced-over AI-generated artworks.”
    • “Got it, started building a few models but kept feeling there was something off about the designs and artwork; a quick look at reviews confirmed the feeling I was having about AI being involved in it.”
    • “Did some investigation and I can confirm this game does use AI artwork.”
  • music
    18 mentions Positive Neutral Negative

    The music in the game is generally described as calm, relaxing, and fitting for the overall theme, enhancing the enjoyable experience. However, some users noted the limitation of having only a single soundtrack throughout the game, which could detract from the experience for those seeking variety. Overall, it serves well as a backdrop for players who enjoy listening to their own music or podcasts while playing.

    • “Incredible sound effects and great nostalgic music, really great game that delivers on everything it needs to be!”
    • “The music is relaxing, the sounds are satisfying.”
    • “Only gripe would be the single soundtrack that plays through the whole thing.”
    • “Relaxing content if model building is your thing, I may only have 2 hours into it, but with the background music muted and my own music playing, it took me back to a simpler time with the Gundam kits as a kid.”
    • “Music is relaxed and fits the theme, making for an enjoyable experience.”
  • grinding
    6 mentions Positive Neutral Negative

    Players find the grinding aspect of the game to be time-consuming and tedious, particularly when needing to rebuild models from scratch for minor changes. The process of snipping and assembling pieces is repetitive, yet some users still enjoy the overall experience despite the grind.

    • “Instead, if you change your mind or find you made a mistake, you have to rebuild the model from scratch. This is both time-consuming and tedious, especially if all you want to do is change the color on a few bits or don't like the decals.”
    • “Basically in each 'level' you tediously snip all of the pieces off of a section, affix them to each other using the included guide, and then do the same thing with each next section until you have a completed mech.”
    • “Runs great on the Steam Deck... a bit tedious with the snips and a few things, but I really enjoyed myself.”
  • emotional
    4 mentions Positive Neutral Negative

    Players express a strong emotional response to the game, highlighting feelings of disappointment and heartbreak, particularly after investing significant time only to feel let down. The sentiment is compounded by the frustration of missing the refund window, leading to a sense of regret and disillusionment.

    • “It was heartbreaking to find out after completing over 50% of the game and just going past the time limit Steam allows for refunds.”
  • story
    4 mentions Positive Neutral Negative

    The story has been criticized for its inconsistency, with users noting that it does not align with previous statements made on Twitter. This lack of coherence detracts from the overall narrative experience.

    • “This story still does not match what he said on Twitter.”
    • “His story is not consistent.”
  • monetization
    2 mentions Positive Neutral Negative

    The monetization of the game has been criticized for feeling like a cash grab rather than a genuine passion project, leaving players disappointed in its approach to in-game purchases.

    • “It really surprised me because you'd think a game like this would be a passion project for someone who really adores Gunpla kits, but unfortunately, it very much feels like a cash grab.”
  • humor
    2 mentions Positive Neutral Negative

    The humor in the game is subjective, with some players finding it amusing while others may not share the same sentiment. Overall, the comedic elements seem to resonate differently among users, leading to mixed reactions.

  • stability
    2 mentions Positive Neutral Negative

    The game runs smoothly on the Steam Deck, providing a stable experience overall, though some users find certain elements, like the snips, to be a bit tedious.
