I'm glad the fire/air movement comes across well :)
Yeah, I pumped up the flammability of the grass for the demo. I want to add a) more dangerous enemies and b) spells/abilities that are a bit less likely to destroy you - laser beams/lightning that can catch things on fire, but not necessarily near you, physical projectiles...
Longer-lasting spells to protect yourself from the consequences of your actions are in the cards too, so that you can be running around in fire (for as long as your mana lasts!).
Thanks for playing!
