I'm just kidding btw lol, after playing for a bit with my dpi down it's really fun with friends, although idk if it's a bug or not but when me and my friend finish the first level it doesn't unlock the second.
yeah of course, the only thing we had trouble with at the beginning was the difficulty of the enemies but after a bit we were able to pass the level pretty fast, so many you could add the ability to change the difficulty?
