One Monster RPG: Running out of slime

A game made for the GMTK (Game Maker's Toolkit) 2019 game jam, later updated to improve the game. A game where our seasoned hero is mere inches away from gaining enough EXP to reach Level 100. But oh no! There is only one monster left in the world, and this mere cannon fodder won't drop enough EXP for our hero to level up. It's time to think backwards, and feed the enemy for it to grow before you strike it down.
