The nasties come at head, chest and feet height, and you can duck, jump or blast your way through the caverns ahead. A jet pack is also at your disposal a little later in the game.
The graphics are very good, and run along the line of the main character in US Gold's older titles such as Scooter, Ollie's Follies and Ghost Chaser - except they are much larger.
Overall, a nice jump-shoot-collect game. A sort of Ollie's Follies in Hell.
