    • “2024 has been a feast for us metroidvania fans and this game stands out from the huge pool of other options this year with its unique setting, story, and overall charm.”
    • “The story and characters are quite amusing and I got invested in saving this dog.”
    • “It's got humor, charm, adorable cell clusters you can push around that make cute noises when you tread on them, and a surprisingly heartfelt story about a vaccine giving his all to help destroy a virus infecting the dog whose innards make up the very novel world you traverse.”
    • “Unfortunately, some missions are more or less simply checked off as completed without the character giving the task having much to say.”
    • “You can also acquire quests you just can't even complete because the quest and areas aren't even finished.”

Once I realized the train system was there as a hard divide between areas, I felt a little let down.”

    154 mentions Positive Neutral Negative

    • “The gameplay is very fun and the movement is responsive, so combat and exploration never get boring.”

    • “The mechanics are fun and addicting, the map and menus are very user friendly, and the difficulty is just right.”

  • optimization
    80 mentions Positive Neutral Negative

    The game's optimization has received mixed feedback, with many players reporting performance issues such as stuttering, frame rate drops, and long loading times, particularly on the Steam Deck.

Overall, while the core gameplay is praised, significant optimization improvements are needed to enhance the experience.

    • “The game has a few challenges with optimization and some gameplay bugs in the latter half of the game (to be expected with early access), but make no mistake, this is a full game (as you can probably surmise from my nearly 35 hours of gameplay at the time of this writing) and one that you will greatly enjoy.”

    • “It isn't optimized, so performance was an issue at times, but the developer acknowledges as much.”

    • “Surprisingly, I had to do dedicated grinding to buy one of the final upgrades for like 3 more minutes.”
    • “Just lost momentum and couldn't finish it due to tedious and repetitive gameplay along with some typical and annoying indie jank.”
