Use arrow keys to move around. Z to interact I guess? Monster Kid has got lots of training from Undyne. He has 800 HP and I forgot how much damage but he poisons you like Sans does. This is just V1 so he only has one attack right now. Remember to sign out before you play this or I may become your stalker =) Just kidding! V2 will be coming out soon, V1 is horrible ;)
Pococikipusta make the battle creator witch I used to make this. I give all credit to him. Including the sprite. Check It out! its under this fat box thing.
