I really enjoyed your game and had a lot of fun playing it! The controls feel smooth overall, but I agree with some of the other comments about the wall jump—it’s pretty tricky to pull off. I’d suggest making it so that when you press space near a wall, you stick to it until you release the jump button, rather than being pushed off immediately. That way, it would also give you more time to place a block if needed.
There are also a few spots where it feels like you need almost pixel-perfect jumps or block placements, which can make things a bit fiddly at times.
That being said, I really like the game concept, art, sound effects, and music and the option to change the controls is also very nice!
