This outdated version is proving more popular than the far better quick chessyness version so I removed it as it’s embarrassingly bad at chess.

As of 16/08/2022 this has been surpassed by Quick_Chessyness https://adam-howell.itch.io/quick-chessyness A faster snappier and more powerful engine.

Simple Pico-8 chess engine. 

1.5 A number of fixes and improvements making a stronger game (15/08/2022)

1.4 faster, stronger, but still dumb. (13/08/2022)
1.3 Fixes en passant and other bugs. Adds significant speed optimizations and stores the open book as strings so it can be larger when staying within the Pico 8's size limits. Otherwise should play at the same strength as 1.2. (03/08/2022)

1.2 Plays a much stronger game now. However, still makes some silly moves.

- Looks like 1.2 breaks en passant. I'll fix it when I have time :(

1.1 Now with added mouse support!!!
