If you click a spell with no use on the current level, such as "Identify" when the level has no potions, you become unable to use spells for quite a while. This is game-wrecking.
It's intuitively obvious that morality does not come from an external command, or from any conscious decision; rather, morality comes from the heart. The nature of the heart is determined by genes, therefore morality is genetic.

Needs an undo - it's really hard to figure out whether a tile will be in gun range, and rather frustrating to have to restart whenever you misjudge and move into a position you can't shoot from.
The animations are a bit loose - this game could benefit from animations that more accurately reflect the characters' hitboxes. Doesn't hurt the game much, though. 4/5
Actually, those Flash games that are laggy (only a few, I still consider it a strike against this game) seem to only be laggy on Chrome. It's worth trying a different browser if the lag is bad.
