Lichtspeer's theme is a unique combination of 1980s lasers and neon with...Germanic themes? You're summoned by an ancient Germanic god to launch your spear of light at endless hordes of enemies across landscapes including desert temples for his amusement.
The game is incredibly ridiculous, and the faux-German text littering the game, along with the German names you have to give your character, provides the whole experience a unique flavor. I also like the Lichtspeer death counter: your character name keeps increasing in Roman numerals depending on how many times you die, so you could be Helmut CXXVI, for example. It's a subtle but funny thing that goes a long way to help out with the theme of the game. Oh, and the currency you earn, Licht Standard Denomination, is just so coincidentally acronym'd LSD. Hmm. The whole game is goofy...yet grand, in the way that you have to deal with pirate vikings and hipster ice giants.
