i dont know but you certianly have to play for quite a bit to come to the end if there is one and with a bit i mean hours if you arent a speedrunner or just really really good at games since this can be pretty difficult
around 30 min the final boss spawns, you can continue for endless but after that the game lags so bad that the enemies don't take every hit you deal and 1 shot you and won't die from the revive 1 shot nuke
