I have implemented diagonal movement for player and enemies. That improves the game balance by making it much more difficult, as now it is dangerous to be sorrounded by enemies. By being sorrounded by a group of eight ninjas you could receive up to 48 damage per turn.
Also the touch controls have been updated for diagonal movement.
If I’m able to iron some bugs I’ll upload the post-jam version in a couple of hours. In the meanwhile you can play the original jam entry HERE and leave some constructive input
