Is this testing for boredom in players?
The "puzzles" (if they can be called that) are mainly just simple and simple to slove but are dragged out so you've solved it in two seconds but thanks to serval gameplay flaws it takes much longer than it should.
Besides, your main idea (putting the greens walls in inconveant so walking into the wrong one which is normaly in front of your goal sets you back) is really easy to figure out so makes your first 10 or so stages moot. and because they take so long this doesn't m ake your want to persist for longer.
And its not hard to figure out where your inspration came from (Blue+Orange, Portals, Testing...I could go on. I was half expecting a evil A.I to gas the scientist) but it is hard to figure out where your shcooling came from. Don't you know what an emzyme is?
Also why did you make it so Blues gun is Rapid Fire in mid-air? if you hold down Space in mid air its fires faster than if you hold fire down on the ground. Try it.
