I like how the destructible platforms cause the player to spring up into the air when you land on them with a normal jump. I also like how landing with a double jump destroys it and causes you to keep falling down due to the extra force you exert. However, the sound when you fall through seems to be playing more than once, causing an echo effect.

there is a lot to like about this game, one being the artwork, I like that you lift up in the air when you land on a destructible platform, maybe it could disappear in a more interesting way eg if the logs were floating on water, and you land on a vertical platform it could sink a little like a trampoline, lift you up then sink and make a splash, it might be quite difficult to do but looks like you have some skills with animation. 

Very interesting! However, I never got to the finish line :)
