Kixeye, it's extremely rude from you to just stop the game because some people ( including me ) invested a lot of time into this game. I WILL NEVER PLAY YOUR GAMES AGAIN. cya.
it would have been nice if you could have kept your upgrades when you start the game second time. It's pretty hard 2nd time and the 1st time you finish the game you dont have so many upgrades on . And starting the game without upgrades it's pretty annoying + you don't get to fully upgrade 2nd time anyway.
