This game looks very polished and with great graphics, I like the mechanic of switching colors to block/shoot the enemies of the same color and the skill that goes behind it! My complaints, tho, are the fact that you always move towards your cursor makes the game incredibly difficoult. When I shoot an enemy I tend to hover over it, so the ship goes over it and takes damage. Even if I try keeping the cursor near the ship itself, calculating the shooting angle is a bit hard, so to fix that I would either add a laser pointer that shows you where you are going to shoot, or make the movement a simple directional arrow one. The gameplay loop itself is incredibly fun tho, even if I can reach just the first upgrade for now. So overall, a really great game!
