The gameplay is cool, I like the color matched weapon system. The boss is cool too, you can see when will the boss change color and prepare for that. The visual are nice, the laser attack is pretty cool. The music are nice too.
The first boss is fine, the attack is manageable. But the attack of the second boss is way too fast to react, especially the double circling red ring spawning bullets while the boss doing ground hit attack. It makes the fight more of a memorization game rather than reaction game. In facts, I only beat it because I memorized the safe spots of the double circling red ring attack. And the double battle of the third boss is just too much for me after the second boss.
But still, the overall gameplay and the control are fine, nice game!
