Thanks for feedback you must read my devlog with the on the lastest update issues. There is a trick to the mushroom fight if you burn all the grass tiles the mushroom wont be able to regenerate hp. The mushroom can only regenerate hp when touching grass tiles. The slime has enough mana to throw fireballs to kill the mushroom. The best way to regen your mana is creating a slime puddle on a rock the collide can be stay on top of it
Keep running to a rock while the slime puddle is being created to regen your mana. Any feedback would be greatly appreciated
