Cave In

Game description:

Cave In is an "eat'em" game in which you play a mole. The goal is to eat yummy (at least for the mole, which for whatever reason looks like a piranha) food in each screen while avoiding other animals (which look like a monster).

You can "cave in", which means deleting your path which the enemies usually follow.

While this game does borrow some aspects from games like Pac-Man and Snake, the game has no levels and, like in Berzerk, you can move freely around the screens.
