Yay! I finished the game in 6:36 minutes.
The first door I got is "DEAL MORE DMG BUT LESS DMG". I wonder how that works.
Anyway, this is a fun game. I was really having fun dodging bullet that I forgot to aim my shoot.
I also found some way to cheese the last boss, it seems the enemy bullets despawn before hitting you when you hugging the bottom border. Don't take my word for it though, since I still try to dodge the bullet when hugging the bottom border. I am just really sure some bullet should have killed me in that part.
