damn, i just cant manage to defeat the boss in endless mode.like the guy make 1,5 turns in no time, I jsut cant keep up with that speed :-/
Also, I am still not sure:at which point or with which upgrade does the shotting turn from "press button to shoot once" to "hold button to auto fire"?
With the ACHOO! upgrade, which lowers attack cooldown. I received a few complaints of hurt hands from having to mash at the maximumspeed haha
Just updated a version, I had messed up the frequency of enemy spawns on the boss and make it rotate a bit slower, hope it helps!
