I really like the idea of this game, and the music and timing elements are really interesting too, it just seems very hard right out of the gate. It also seems the fullscreen view works but the game is within a super small canvas, however the game is super laggy when multiple spawners are on screen. Reducing the browser tab window display resolution and lowering my refresh to 60hrtz from 480hrtz helped a lot, but I still miss my shots every once in while and reduce my own health to 0 every time. I really think the idea of eliminating each spawner sequentially is a cool and well though out mechanic, but maybe the starting spawners should have less capacity. It would be cool if the player also had just a bit of direction about how the health system works, and maybe some thematic elements. I spent a few minutes thinking I got shot by something and didn't see it. I think this game is really cool, has pretty good graphics, and well thought out gameplay while doing a lot to be original :)
