Botanic (1983)

A maze game where the player controls a caterpillar, traversing branches of a tree and eating leaves. The leaves obscure various junctions in the maze, so you are not sure if you’re going to hit a dead end until you munch the leaf. Enemy bugs are hunting you as you navigate the levels, but there is a power up you can collect that works like the power pills in Pac-man and allows you to chase and eat the enemies for a short time.
