Fun little introduction to Shogi, and overall well polished.
I'm not a totally new player, but also not very strong. Didn't have much trouble completing the game, as the AI has some odd quirks - it's really weak to an early rook attack on file 6, and will just throw all it's pieces into the hole on c6 one after another.
I felt like the AI would have been stronger than me if it didn't do odd things in response to attacks sometimes.
Fun strange variant pieces - did you invent them?
