The gameplay in Undermine 2 builds upon the original with new mechanics, characters, and a more complex roguelike experience, offering an addictive loop that many players find engaging. However, some users express concerns about balancing issues, missing features from the first game, and a lack of clarity in certain mechanics, which can detract from the overall enjoyment. While the game introduces fresh elements and visual improvements, opinions are mixed on whether these enhancements outweigh the perceived downgrades in gameplay quality.
- “Great upgrade over the original fundamentals — the game builds on the strengths of the first Undermine (dungeon-crawling + roguelike progression), adding new systems that deepen gameplay.”
- “The core gameplay loop is extremely fun; it's the Undermine you know and love but with some new bells and whistles.”
- “Awesome follow-up to the first, more mechanics, more depth, more synergies, more special magical effects, and honestly amazing art style & music yet again!”
- “While this might seem nitpicky for an early access title, these mechanics already existed in the first game, which raises the question of why they are missing here at all.”
- “The art style is great but the gameplay is a downgrade.”

The graphics of the game have received widespread acclaim for their impressive visuals, improved lighting, and charming art style, which many players feel enhance the overall atmosphere. While some reviewers note that the game feels like a graphical remaster of its predecessor, the upgraded aesthetics and smoother animations are generally seen as significant improvements. However, a few players have pointed out performance issues and expressed concerns that the gameplay may not live up to the visual enhancements.
- “Stronger visuals and atmosphere — many players and reviewers praise the improved graphics, lighting, and art style.”
- “The graphics and the art style are very well done and suit the game perfectly. The bosses are pretty cool, and there are 200 relics in the game at the time of this review.”
- “The visuals: a night and day difference with this one being more beautiful, vibrant, and easier to see enemy projectiles.”
- “Graphics are good but performance is lacking.”
- “The visuals look pretty but the gameplay was boring; after 4 runs, I gave up and refunded.”
- “Sequels don't have to be entirely new; don't get me wrong, they can just be better than the original. However, this just feels like Undermine 1 was remastered graphically and tossed back out as early access because they didn't finish the game most likely by a deadline.”

- “My only 'gripe' is that I prefer the original UM1 music (though that's not to say the music in this game is bad; having tracks get more intense during combat is certainly cool).”

grinding

Players find the grinding aspect of the game to be a mixed experience; while some enjoy the potential for powerful builds, many criticize the meta-progression system as slow and less rewarding, with a reliance on RNG for unlocking strong items. The initial grind can feel tedious, particularly with item descriptions and farming bosses, leading to a preference for gold accumulation over other forms of progression.
- “Meta-progression feels weak and grindy — many players criticize the meta-progression system: gold feels less useful, progression is slower, and unlocking strong builds often depends on many runs (crowns, relics, RNG) rather than incremental gains.”
- “Farming bosses is not half as fun as hoarding gold.”
- “An amazing roguelite, but it requires a bit of grinding at first to get going.”

The game exhibits significant stability issues, with players reporting frustrating glitches such as broken upgrades and unintended interactions that lead to game-breaking scenarios. However, the couch co-op mode is noted to run smoothly, and overall performance is described as visually appealing.
- “Couch co-op runs great and smooth.”
- “The game looks and runs great.”

I don't understand how this glitch made it into the game, as the first game was a masterpiece, but this one is filled with these types of glitches. For example, if you hit a relic by mistake, it will break. Why is this in the game?”
- “The game crashes frequently, making it nearly impossible to progress. I've lost hours of gameplay due to unexpected shutdowns, which is incredibly frustrating.”
