Princess Loves Slime

The princess has been missing for weeks! Not a single attempt at rescuing her has succeeded due to the machinations of the cave trolls. As a lowly slime, you've decided you're tired of your prescribed life of harassing newbie adventurers and want to become a hero. Rescue the princess! As a slime, you can absorb other bits of slime to become bigger. However, using your slime abilities will reduce your size again.
