One of the best games of S1 provided you like stgs and know how to approach them. While there may not be much in the way of aesthetics, it's focus on its level design and unique mechanics show you that they don't need to impress you with anything flashy for you to have a fun time. This sort of game is really what I think the playdate should be all about- niche titles with experimental gameplay that wouldn't be able to be experienced anywhere else.

Also, note that the game doesn't loop with no acknowledgment/proper ending. What may seem like a loop with added difficulty eventually leads to more unique levels and a proper ending.
