I like the idea of switching characters to accomplish different tasks. I think the concept was executed well. The first level was color coded to the characters so that made understanding the game a little easier. Interesting little puzzle platformer. Great job!

As others have said I did not immediately understand what to do, I think maybe the yellow bars should have looked more like doors.

However once I understood it was nice to play :)

Took me a moment to realize what to do; however once it clicked it had some good ideas for a platform puzzler, cool concept
