Nice platformer with good graphics and sound.
I liked that all the areas had different look

Very good for 3 hours! you should update this with better platforming controls and more and better levels!.

I really like the idea of playing different characters depending which place you are in, it would be really cool if you gave them different mechanics too!

Your style reminds me of my own, keep making games! I can tell you have good ideas! :D

Really good work! It's cool that you made three different characters and levels. That's a good starting point for a  story, if you want to continue working on this game. Music also really helps create an atmosphere. For example, you could have different music with each character / world.

One level started with no music, and then the music slowly got louder when going further in the level. That's a really nice effect!
