This computer game is called I Wanna Be The Guy. Don't let the title fool you. If you dare to try, this will possibly be the hardest game that you'll ever play in your life.
Anything and everything in this game will kill you. You are not safe. Apples (They're more like cherries, really...), Spikes, Lightning, Airplanes, Zombies...even Mike Tyson will send your little pixilated guy to his messy demise. Yes, you have it right. You are not hallucinating. I even said Mike Tyson.
You can get all the info you need here.
Let's end this on one last thing.
Are you sure you really have what it takes to be "The Guy"?
