Playing as either César or Maurice, the only two characters initially available, you're tasked with defending your dungeon's doom chest from those who would destroy it. (Presumably because any chest with teeth and two heads is probably not looking to make friends with the local populace.) You do so not only by purchasing various traps and obstacles to be placed throughout the dungeon, but by controlling your monster du jour and devouring/blasting/dissolving enemies for points and cash.
Enemies appear in waves from any of the dungeon's multiple entrances. (Maybe you should have picked a less accessible lair?) Using either the [arrow] or [wasd] keys, guide your monster around the screen, and use the cursor to aim, then click the mouse to fire. If you're close enough to a small enemy, you can devour them whole by clicking on them. Of course, you can't be everywhere at once, and so you'll want to make use of the shop between waves to purchase the various items that become available throughout the game.
Wrapping it all up is a warped sense of style that looks like something from MTV's early days, complete with heavy metal soundtrack. All it needs is to be interspersed with scenes of Beavis and Butthead headbanging on the couch. While some greater variation and detail to the enemies would have been nice, Trap Master still manages to stand out and proves what I've been saying for years; you can solve any problem with an acid bath. Especially door-to-door solicitors.
Analysis: But is Trap Master as fun to play as it is to look at? For the most part, yes. While not tactically very deep or what one might term "thought provoking" (unless that thought is RAWR SMASH PUNY INVADERS), Trap Master is a fast-paced, quirky way to while away a few hours. The idea of combining a side-scroller with a defense game is an odd one, but here it works. Trap Master isn't trying to be an intensely strategical title, so players looking for a slow, complex session should look elsewhere.
There are some limitations to Trap Master that keep it from becoming just another button-mashing gore-fest. Initially, you only have a certain number of slots available for each type of defense, traps or obstacles ("devices"), and each can only be placed in particular areas in your dungeon. While obstacles can be used up or destroyed, traps can be upgraded to increase their damage and overall nastiness. You can even upgrade your monster or your doom chest to unlock new and devastating attacks.
But the slow pace at which new items and trap slots are doled out may turn off those of us who are into more instant gratification. The boss battles, which tell a loose sort of story, only occur every ten waves, a shame considering they inject a lot more personality and interest into the game. Make no mistake, Trap Master is a ton of fun. But some more tweaking and a wider scope of enemies and customisation would have made it truly great.
Still, there's something about Trap Master that's appealing beyond its funky aesthetic. Sometimes all you really want is something fun and different to drop yourself into, and the game fills that niche nicely. It does make use of Gamer Safe, although using it isn't necessary to complete the game, and there are still enough challenges and achievements loitering around to keep the enterprising monster busy for a good while. If you've got fast fingers, a twisted sense of humour, and don't think you get nearly enough bone-crunching action in a day, Trap Master will be a friend to you.
