physics are quite complicated, wolfheat. there's a bunch of engines you can implement into your project. -- as for the tutorial: yeah. thats one way to do it. not the most elegat way, 'tho. did you duplicate the obect by script or manually by copy/paste? btw. the "In all your code should look like this"-screenshot is a joke, right?
as for dealing with colorblind players, you could define a unique shape for each color, like red = triangle, green = square etc. --- nice game btw. 3/5
i love the graphics and animations! cusomizable controls would be nice, cos i have to switch to english keyboard layout to control this game properly. --- oh. and this game is HARD. I even fail in practise mode °~° 4/5
