If anyone is really that broke that they can't afford to pay for a game that is often on sale for $2.50, then just come to the game's Discord and explain your situation and I will happily give you a free key so that at least you get the latest version with all the sweet updates that I've spent hours working on. You can find the Discord by going to the game's Steam page. Stop by and chat and that way you don't have to play what I'm assuming is the old shitty version this site is hosting.
I'm not a company, just some guy that makes this game for fun. I certainly understand that not everyone has money to buy new games all the time. Just to re-iterate, if you really can't afford the game, come stop by and talk to me and I'll happily give you a free copy of the legit version.
