Yea the game is in Alpha and the link to buy is kinda hard to find, but it's picroma.com/buycubeworld, and you have to log in with an account to purchase it. I will provide the account, or you can make a
new account. Whatever floats your boat, but the game is tied to the account, so I will
be needing all the info if you decide to make the account.

They only accept Paypal or credit cards, neither of which I have at my disposal
easily.

Basically if you wanna do this, just PM me and we can figure out the details, shouldn't be hard really.

Also, if you've done other trades or business here on the forums
I have no problem paying first.

EDIT: it would basically work like this

I'd just give you my account name+password for the site (there is nothing on it, no sensitive info or anything to steal, just a vanilla account)
You'd purchase the game on the account (game is tied to the account)
I'd just change the email+pass of the account after the process is complete
