SHOVELBOY is a retro-style platformer where you have to collect shovels in 21 pre-defined and increasingly difficult small levels.
Each level contains one shovel, which allows you to dig to the next level. You get three lives at the start of each new game, which you may lose by falling into spikes, or been hit by one of the enemies.
In easy mode, you can continue your run after you lost all three lives. In hard more, you have to go back to the beginning!
