Luna Crabs

Description
Very simple game with very simple controls (left, fire, right). Don't expect a title screen, menus or even settings. The action starts right after the game is loaded.
You're located on one of the Saturnian moons where you are prospecting for minerals. Thankfully, your vehicle is armed with a guided missile cannon. The moon isn't vacant but inhabited by aggressive crabs. These creatures are descending from the horizon near to you and then they starts shooting deadly acid balls. After some time they return back and then down again (unless you kill them, of course). Your only defense is side-stepping and firing. There is no real level advance, only new hordes of Luna crabs and 5 lives in your possession.
