Happy Wheels presented by Total Jerkface is the game for you if you want to go "lolwtf?!" (link is full game, not demo)
Happy Wheels is a game where you race to the end of the level while trying to survive. And in some of these levels, thats way easier said, or just way more fun, than done.
First off, my favorite thing about Happy Wheels is that ALL the levels are user created. Everyday you have new levels to play on, some suck, some amazing, some just make me flat out go "What the fuck am I playing?!" Never the less, theres always something new to play and it never gets old. And on top of everything, YOU can make a level too!
You have an interesting selection of characters: A hobo in a rocket wheelchair, a guy on a segway, a father and son on a bike, an overweight woman in a scooter shopping cart like you see at Walmart, and just recently the creators of Happy Wheels added a couple on a motorcycle. Some of the characters have special abilities, the hobo's rocket wheelchair has a fully rotating rocket you can activate by pressing space and rotating with the arrow keys, the guy in the segway and the lady in the shopping cart can hop by pressing space, the father and son on the bike can stop using space (actually very useful in some levels) and theres a way that you can kick the kid off the bike (not sure how though), and the couple on the motorcycle get a little boost by pressing space.
Heres where you can tell, just by playing this game, if you're going to hell or not. Each level does not really require you to make it to the finish line, and most creators do all they can to prevent you from doing that. Theres bombs, land mines, nails, traps, arrows, random obstacles, everything. Now all the characters can take a lot of abuse, in fact as long as your heart, head, and something holding you on to the vehicle you're controlling, you can just destroy these characters. You can break their bones, rip off ligaments, throw them into nail traps, anything you want! It's all horrible and hilarious! The most fun characters to abuse in my opinion are the father and son and the couple. You don't need the person on the back to survive to win, you just need the person driving. This leaves your little fucked up mind to do alllll sorts of messed up things to the passengers. And the worst part is you can't help but to laugh at some of the stuff happening.
Overall its a great time waster. There are no high scores, noachivments to unlock, nothing like that. But for something to just pass the time while you're trying to get through work or school or just bored in general, I highly recommend this game for a few giggles and hours of fun.
