RGBY Rush

First of all, sorry for the enlarged canvas. This was set up for mobile game. Do play in fullscreen mode to have a better view of the game. Again, sorry for that.

--Instruction--
Click the left button to shoot.
Use the 'Q' , 'W', 'E', 'R' to change color respectively as shown from the icon.
Choose the similar color dino to the same colored enemy to destroy them. Be warned, if you shot an enemy with a wrong color, they'll get harder to kill.

Enjoy.
