Does a good job of emulating the NES era of gameplay. Graphics and sound are solid and the controls are pretty tight. The main problem is that the the game is making fun of horrible gameplay design but it does this by making its game a collection of ♥♥♥♥ moves. Crazy hard platforming, annoying enemy patterns, small invinciblity window after taking a hit and a small life bar. Oh and the skull blocks, If you touch a skull block you die istantly and there everywhere! its insain.
As annoying as all this can be, each level does gradually ramp up the challenge so you'll be able to get a bit of a feel of things before they go from hard to insain. Most of the deaths feel tough but fair. though sometimes you will take a hit you couldn't see coming. The game stops just short of being a Troll.
If your a fan of the nerd then theres lots of winks and nods to his show and plenty of foul language and poop refernces and each of the levels are built around his rants on various games over the years.
The game is challenging but can be fun just make sure you know what your getting into.
