CombMaster

In Comb Master you have to explore a spacious system of caves which have the shape of a comb and are located on the game field next to each other. Your goal is to explore as much combs as you can til you die due to enemies living in the caves.
You also gain money for each game which you can spend in the shop for additional mission equipment like power-ups or a radar revealing the combs arround when used.
