Game starts: "GAME OVER"
Very straight-forward and honest game. I noticed nothing odd about the controls. You get only one life as it should be (you shouldn't be putting bucks into arcade machines). It's also space shmup which is one of my favorite genres.
Extra points for using vanilla JS instead of bloated wasm engine libraries. Also didn't try to come up with "creative" ways to get away with the spritesheet limitation so that's cool.
Would be nice to have more complex enemy/bullet patterns and maybe powerups too. Got a score of 40827.
