The game was super fun! I put together a lil list of stuff I really liked and things that I think could be improved upon while I was playing.
Likes
-Huge sparks flying on kill is a really fun effect
-I really liked how some of the early learning puzzles let you learn by failing the first time. It created a meaningful connection to those specific applications of the mechanic
-Puzzles felt very thought out and deliberate. They weren't annoyingly difficult, but a few of them made me stop and think for a bit which is perfect for a puzzle game IMO
-Art looks great and the sprinkle of background tiles like stones & sewer grates really sells the dingy feel
-Sfx are really satisfying and feel very responsive to player actions
Possible Improvements
-I love the enlarged player sprites, but it feels a bit weird moving around as them due to them being forward facing.
-Off-beat skeletons would feel a lot better for the player if they had some kind of visual indicator that they were currently off-beat. I felt like it was almost impossible to tell until I went up to one and realized. The mechanic itself is really interesting, but there should be more information for the player.
-Having to manually reset on death is probably intentional so the player can think about how to improve, but it feels off the first couple times when you're expecting to be put back at the start of the level, but nothing happens
All in all the game was really great and it's super impressive how much polish and content the game. It would be a serious effort for an entire team, let alone a single dev!
