An interesting blend of mellow aesthetics and palm sweating platformer! A very unqiue combination worth exploring more! :)
If I had to improve it I'd make the controls simpler. Perhaps I'd replace the up button with spacebar, so it's spacebar to jump and once aligned with the ladder pressing spacebar again performs the same function up currently does.
Which platformers are most similar to this? I want more :)
Check out my entry for something... completely different! :D
