You're right that it is a minimax, but the search depth is about 3 moves and the heuristics are a bit random (some opponents will try to maximise pieces on the edges, others may try to minimise king height, for example).
Like the theme and the different movement options! Game is a bit too easy though imo. Sliding feels too strong - there's nothing in the game to stop the player from repeatedly sliding until end screen?
Beat the game twice in a row! Love the feel and flavour of the magic. Mysterious, great sense of the unknown. Don't fully grasp what some glyphs do - mostly got by on avoiding combat and metre management. Also, some neat visual effects in there!
Chalk and cheese meaning two unrelated things - so zachlikes and sokoban. Cheese sounds like chess; chalk sounds like szachy (Polish). Chalk - drawing; MS Paint-ish interface and white instruction symbols.
