I LOVED this. The way you were able to make the jump sounds mesh with the background music no matter how many layers of the track you created really impressed me. Im not sure if you could go in any order but the order I unlocked the switches sounded perfect.
Such a good and engaging game. Can't wait to see what happens to these two guys. My ONLY critique would be a little more character dialogue. With two main characters and no npcs you could have a lot of fun with little moments as they go through the level.
Really just a small critique though. It was so good!
