Pretty fun SHMUP! The game could have used a pause function and the Wave 3 boss had way too much health, but aside from that it was a fun and short experience. Congrats on finishing your game, Melonodev!
If there are others who have problems with the health of the 3rd wave boss as well (and/or maybe the final boss?), hit me up or reply here. It means I made a mistake and I'll get a new version up with its health turned down.
