Fair point here. I agree that the combat is underwhelming, and that there could have been more puzzle interactions. I had big plans for puzzles that utilized lightning (interacting with water, powering generators / machines, etc), but as is typical with game jams, time prevented it from happening. Lvl 2 spells have a larger area and deal more damage. I also intended to make them actually behave differently, but time again.
I appreciate your constructive feedback!
