Hmm...your game has some nice ideas, but it has some problems.
First, I think the yokai attack you based on a timer, right? That means the best strategy is simply connecting as many 3s as possible instead of looking for the best possible move
Secondly, I think your game doesn't qualify as a dungeon crawler as stated by the jam rules?
- The game must have step movement on a grid. Smooth transition between grid squares is allowed. Half-steps or dividing the square into smaller squares is not accepted.
Maybe ask zooperdan what he thinks about this.
