Hadn't noticed lag with the fire wand, but it makes sense since it's just making a ton of instances of a projectile class, haha. I had plans to make it particles with just one hitbox, but never got around to it.
And the bubble was definitely my favorite mechanic! I could really see it being fun in a full game, and kept thinking of cool uses for it (that I couldn't do in time, or that didn't really fit this particular game) while working.
Thanks for taking the time to play! And the feedback is great!
