one problem with the game is the fact that there is more then one solution to some levels, and it won't let you use them. It is literally a simply matter of moving a couple of pieces over a little bit but it looks exactly the same.
Actually redeemer, the 3D6 weapons does three to 18 damage, it simulates rolling three six sided dice for damage. a weapon of 3D16 would do 3-48 damage. It is not a bug, it simply is a throwback to tabletop games.
Not bad for a first game. Sure its really common and simple but if you continue you will get better at it. no one excepts a masterpiece for someones first creation after all.
