Nice work on your first jam game!
I really liked the concept and presentation of the game. The idea of having to draw these spells to do stuff was nice, but also a hard at first. I am also kinda lost what the actual goal of the game is.
I managed to use the drawing spells to push the appearing ghosts/enemies away but never managed to kill them. Eventually I would always die, because they kept coming.
I think pausing the game completely while drawing could have made it easier. Together with adding a healthbar and instructions how to beat the game could make it a great/better game!
