Hi, as promised here's my review: The game gives me super meat boy / N++ vibes, the controls I feel like they're a bit floaty but you can be precise if you are good (disclaimer here: I might be biased on the difficulty/control part because I play a lot of Celeste modded... platformers don't get much harder than that). The difficulty I think was fine up to level 11 (which isn't too hard in it of itself but I feel like between level 10 and 11 there was a bit of a jump).
I like the style of the game and how it overall feels responsive, here are some suggestions and feedback:
- I would add an animation for the wall climb (otherwise it feels like the player just slides up the wall).
- (This is my main suggestion) I would not start the countdown until the character starts moving, this way you give the player some time to carefully analyse the level without it having to cost a death.
Anyway this is what comes to mind, overall pretty fun and enjoyable game for me, Good job :)
