I meet the one of the bug in the known bug list. It's the one where I can shoot both bullets type at the same time after transforming while shooting the bullets. This bug make the game a lot easier. I didn't encounter the other bugs though.
The straight forward bullet will stop shooting if you keep pressing the shoot button after a while. Dunno if this is intentional or a bug. The problem might also be on my end since I'm using an old machine.
The playable character hitbox is too large for my taste. It cannot fit in the gap between the enemy's bullets.
That being said, I actually having fun when playing the game. Good work!
