Lovely graphics, fun game! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

Awesome moody presentation.

oh, yeah, and interresting choice of color. It works surprisingly well!

The recoil feels really good when you shoot! ^^

I would have liked more ennemies and some bonuses to add variety to the game. =)

Also mabe the game should become harder over time, that way the player would end up dying eventually. I felt like i could play forever so i just stopped playng at some point.

I really liked it!
