Fun concept, though a bit confusing at first to figure out (thought right/left referred to mouse buttons). I enjoyed jumping across platforms.
I'm unsure what the ticking sound is meant to represent. I know it's related to a bar on the UI going but, but the UI is not very clear at first glance - what is the multiplier for? What is the red bar? It doesn't seem related to health, as it's full when I die from being hit by monsters.
It's not clear when the witch is charging her spell without the text telling me she is.
Love the procedural generation!
