I love boss fights, so I'm glad you made this type of game! I like that the boss becomes more dangerous as its health lowers, but it would be cooler if it started using different types of attacks besides shooting the same shots faster.
This is a nice looking game. Simple graphics but attractive.
I like that the player has 3 different power modes, and each is useful. However, the damage mode is far more useful at the start of the fight, and the slow mode is far more useful at the end. It would be nice if each mode was still very useful throughout the whole fight, even if particular ones shine more.
My finger gets tired after a bunch of clicking. Enabling autofire would be appreciated.
