Alright, so I decided to download it and have gotten a bit far in it. The gameplay is just like Super Mario Bros. even with the jumping up and hitting blocks from underneath. The only difference is the levels randomly change as you continue playing in real-time, and consequently, so do the enemies. I got so far that it got to the point where the levels went from happy-go-lucky sunshine to hell on Earth. I'm suddenly being chased by something straight out of Stephen King, this red mist or whatever with demonic creatures flying out of it, enemies bursting into splashes of blood, giant claws coming up from the ground, platforms crumbling underneath and this creepy 8-bit tune in the background.
I also like how when you die, there are no lives.. you just keep respawning from a checkpoint until you've gone insane and willingly give up. Even the game itself likes to poke fun at your misery every time you die.. "Ready! To die.", "Give Up.", "Behind you!".
This is a beautiful, pixelated nightmare. I like it.
