I will definetly work on the game after the JAM. It was a fun experience trying to make a game with in 4 days (as my first big game jam). And the / and - tiles was suppose to work by operating smaller number into bigger when dropped inbetween two tiles but the drop area got mixed up and it instead give me some funky results will look into it soon.
Appreciate you trying the game. I loved your game by the way!!
