I'm glad it's not exactly like R-Type where I die every 5 seconds, or I use to ahahah. It's a really nice entry for the this jam. I don't know if recognize the following games: Summer Carnival 92 Recca and Gun-Nac. Both are NES games. I really advice you to play them, because for the limitations of the NES, they were very well made, Bullet Hell shmups. Although your game is small, just like mine (It's also a shmup, but more like Space Invaders), it was very enjoyable! Well Done!
PS: If you have the time try my entry. Cheers!
