hey, what specs does your computer have? Also, can you describe the errors better, does the game work and is laggy? where does it say pvp demo, what is the error...
5 star game, VERY fun. Had what seemed to be a bug with the red key, opened the door, had enemies inside so i backed off and the door closed up, which asked me for the red key again, which i had already used.
thats awesome to hear! thanks, and yess, its indeed very much a work in progres. HP is a thing, but you got so little sometimes it is indeed a one hit death, like on robotron.
