Sure I'll go. Really liked your game. In particular I liked that the different past versions of your character are color coded. I played a game with a similar mechanic to yours but all versions of the character looked the same so I found it impossible to figure out what way going on.
One thing to change, and it's a minor one, in the second to last level I found jumping to the button on the platform is just a bit harder than it should be. I think it needs to be just a tiny bit lower.
