This demo was exceedingly short, with only 3 levels, but from just that I could see some things:
the 3d graphics were nice, and the levels were built well. However, the game has a tendency to run slowly and with lag, and on top of that, the level complete/ crash screen was doodled on and unproffesional looking. The game has good potential, but needs to be altered a little.
Although this is a very good game, with amazing graphics and realistic physics, I'm sure many others agree that it is a horrible thing to see many features only appear on a certain site. Take my advice and make all of the maps and guns available to Kongregate as well, many people will love you for it.
If you like MARDEK in the slightest bit, possibly because you are sane, or you just want to bask in Psuedolonewolf's awesomeness, then join the new fan club!
There are just a few things to improve the game. 1) A Fast Forward button 2) A Fast-Fast Forward button 3) It shouldn't be timed, but deployed when you are ready 3) A way to make straight lines would be nice 4) Nothing else, this game is awesome!
