This is pretty fun and polished! However, sometimes you get in an impossible situation where the next enemy color you need hides behind a different color, so you are forced to break your chain to survive (which makes you take damage anyway). This could probably be fixed by making the enemies spread out to the sides more, removing the damage consequence for breaking the chain, or spawning the next enemy you need on an empty direction every time.

@PicoCoder yeah you're absolutely right... but i'll be too lazy to find a solution and i say ....mmmmh it's okay it's not too bad
