Death is out to do his job, and instead of going after cute things like bunnies or people who think aliens aren't real, he's hunting demons! And you get to help! Demon Decimator is a great little puzzle game from Pixelulsar uses the sliding block concept to craft 20 levels of smart planning, testing, executing, and the other kind of executing, all in the name of tossing demons into pits of lava. Neat!
Click on the box-like demons to select one, then tap the [arrow] keys to slide around the screen. Demons continue to move until they bump into a solid objects, so in order to position them for a clean slide into the liquid hot magma space, you'll have to knock them about the stage first, using the walls to your advantage. Later levels introduce things like movable walls, buttons to retract barriers, and keys that must be collected in order to open the lava grates.
While you're doing all of this sliding, your moves are being counted. You're also being timed. And if you mess up and have to restart the level (press [R]), that's recorded, too. Once you fight your way to the end of the game, you'll be shown a final tally. There's no high score board or anything to compare your results to, which is a micro-sized bummer, but then again, maybe it's best to keep that embarrassing final count a secret.
Good for half an hour or more of challenging but not frustrating fun, Demon Decimator is the best way to kill demons without getting black demon blood all over your monocle. Plus, it's a good puzzle game, too!
