This is fun! Such a simple idea, great execution, I love it!
It would be cool if the game had something like jump buffer (it’s basically when the game remembers you pressed space for like 0.2 seconds and jumps as soon as it’s on the ground), because I often times didn’t jump when I expected to be jumping because I technically was still barely in air (this is just a personal preference related to my skill issue :D ).
Anyway, I think you did a great job! I also really like that the platforms are actually a sleepy face which even is animated! :)
