What a nice game ;)
Gameplay:
I love the idea of color switching and door puzzles and even though I'm not good at logic games it was a lot of fun. Everything worked pretty well, the only problem I had was with portals as I really couldn't predict what they will do. Also when I quitted the game then I couldn't close my tab and I couldn't do anything with my browser, you hacker :P PS: Checkpoint system is amazing.
Graphics:
Graphic style is really wise and makes game enjoyable. I would just add a little of juice, like particles when we hit different objects and when we leave portal. The fact that you respected color blindness is also stunning.
Audio:
Sounds are well fitting, but I've lacked a music a lot. Even a really peaceful track just composed of few notes. It would give a lot of mood to that game. On level 5.1 I could make my own song by going from left to right and hitting those color changers, it was fun :P
Innovation:
It's definitely a well made idea (there are many games that make use of colors), but yours is not only well designed, but also it gives a lot of room to creativity.
Theme:
I get the bounds reference, but as for leaps there I can see only portals (so it's not something that follows us through entire game).
In short. A great game that really made my brain grow a little. Thanks :P
