The power of simplicity... Great job...
Reading the page i didn't think the limitation made much sense... but when playing it felt great...
Dodging only my color was a twist for me, since usually in this type of design your own color is your ally... My own color was so attractive that really felt like I was hurting myself every time I picked it up.
The gameplay is quite addicting and the music helps a lot.
I didn't even cared about high score at all... It was just fun to dodge my color and chase after the other colors.
I think I would love an "Survival mode" instead of a "Score Mode"... Where your objective is just to keep playing for as long as you can... with some mechanic to regenerate life that would extend the run.
