Hey man, thanks for trying out our game :) This is definitely the way to die, trust me :D
About the cheese, definitely right. Some sort of better enemy AI would make it way more interesting to play. And about the bomber: in this build it doesn't scale the explosion size. But on our dev build we added cluster bombs, so multiple bombers stack into multiple clusters of explosions 💥
A title screen and proper menu would go a long way for sure, but as you said, for a week we got a lot done on the gameplay itself and kinda forgot about some basics😅
Thanks again for your feedback, and maybe we can play your stuff in an upcoming jam?
