The premise of the game is you are "combining" two different tiles to make a new one (the recipes being shown on the right hand side of the screen).
The UI on the left hand side of the screen shows you and tells you what tile you currently have in your hand to place down (can be a : house, farm or shield generator).
The corruption spreads every 8 rounds to further limit the players options.
The goal is to simply score as high as you can via upgrading tiles which give a certain amount of points depending on the upgrade.
We wish we had more time to implement a tutorial that would have answered all these questions, but with just the two of us and having never made anything like this before it just wasn't in the time table.
Thank you for playing!
