Amazing artwork.
I do like that the grazing dynamic is so explicitly stated from the start; especially like that visually the ship indicates when a bomb is ready. I don't remember many shmups (I played) that did that.
Now, I don't know what era of retro aesthetics is being emulated (definitely pre-Dreamcast) but I feel the SFX is probably the weakest bit. They felt unfitting, if not undercooked or completely absent in places I'd expect audio feedback.
Lastly, and do call me old-school, but I'd still prefer if the game world was presented in 4x3 tate. The narrow viewport just feels way too restrictive.Overall, for what it is, a decent little gamejam demo. 👍
