yet another grid cannon

Implementation of Tom Francis's grid cannon.  This uses the new rules. I found that most of the grid cannon implementations out there uses the older rules.

Cards from https://greebles.itch.io/pixel-plebes 

Not the best choice of cards since the game uses color, but it's cute.

The game isn't complete in that nothing happens when you win or lose, you'll need to close and reopen the game. There might be some very rare softlocks too.

I started this to try out concatenative programming, and decided to mess around with 8th. Never got around to finishing it, but thought it's complete enough to upload anyways.
