Cool concept for a game! The art update looks good, although I thought the sprite work from before was charming. SFX and music sound nice (although I think the music stops looping at a point)
I think the game had a good difficulty curve up until both the knight and rook are playable at the same time. I feel the mechanic of pushing the knight while it is standing on a box should have been tutorialized, but overall, good stuff! :D
