Great game, lovely graphics and DAMN kids with icecream !
Played with controller on web which worked like a charm. The biggest issue was the lack of knowing what to do. I was sure you forgot to add a points scoring mechanic as I kept getting +0 and mixing the paint didn't seem to do anything either. It wasn't until I hit a purple guy while I had purple paint and I scored points that I started to understand the game. After that I finally managed to score some points.
The game should either ramp up in difficulty or have a set goal in order to have a clean ending. Now the only way it ends is to have a kid get to your painting AND not get killed while it does it's 8 second countdown which is more time than you need to get back from the top to the painting so you will most likely never lose.
Didn't feel the theme much in there but the special object was shining bright !
Great job on the whole thing!
PS: I think it's intentional, but the buttons feel cut off on the right. I thought there was a fullscreen issue but it's also showing up when not full screen and nothing of the text is chopped off so my guess it's intentional but looks off. Could just be me also :P
