I like the idea of a space invader, even if it lacks a bit of depth (item, new enemies, different levels...) I guess the 72h time limit of the jam didn't help! :)

I think I've found a soft spot, I can kill enemies without their missiles hitting me!

I see you've used game maker studio too, I feel less alone :D Try my game if you get the chance!

I had fun trying to get as many ships as possible in my squa

Nice game !
