It's a great concept and I'd really like to see it be iterated upon. The puzzles, while easy, were a bit obtuse since it's not clear which doors can have which colors. The meter for altering objects took a little too long to come back, I had to wait for it to increase a few times before continuing. I didn't like that you have to start over if you die, especially since it's not clear how much damage you'll take from acid (I died twice on green acid).
Pretty neat game though, well done!
