Controller drift (my problem I know, but a common one) makes this very hard - adding dead zone would be nice :) Also adjusting the blocks to be easier to jump up to would make it less frustrating, otherwise great!
Thanks for the feedback! In development, I thought of adding fall damage and a dead zone but I didn't really come to it. Try maybe playing on keyboard and mouse which makes it a bit less fustrating. Anyway, thank you for playing!
