This game is fantastic, well done! I haven't finished it yet, but I'm really enjoying it - the design of the puzzles is such that I have to think about the levels instead of just making 'obvious' moves, and it's very rewarding when I beat a level!
One small bug (or quirk, I guess): if you push a bandit underneath a coin, and they both fall some distance, the bandit sfx will play every 'frame' until they stop falling. This can be seen fairly easily in this level:
[......[
[......[
[.....0[
[.....#[
+.b.0..+
[.bc#..[
[#*#...[
[....#.[
[......[
[....#.[
--------
if you push the top coin right, and then right again after it falls.
