Farming Mushrooms in LOWAS

This is a snake-like game for NES, inspired by Homestuck's LOWAS walkarounds The Heir of Breath is helping some local salamanders farm some mushrooms. Once in a while (spoilers: after every 5 mushrooms) imps will appear. Touching an imp will make you lose a salamander (it probably ran away from danger). If you lose all your salamanders (or if you collide with the walls or with the salamanders) it's Game Over. To make things more interesting the game gets a little bit faster after every 10 mushrooms.
