So you've mastered Mario, beaten dracula countless times as a Belmont, know every single platforming trick in the book, seen what humanity has had to offer to challenge your jumping skills...
...not until you see these two games.
First, introducing 'Eversion'.http://zarat.us/tra/offline-games/eversion.htmlIt looks very cute, like every other platformer ever invented... at first glance. The story is simple. The princess is kidnapped. You must save the princess. As you finish the game (which takes around 2 hours, it's very short), you'll find that you have to switch between the different realities of each level through an 'eversion'. Everything seems to be the same.... except it seems... darker.
It's very H.P. Lovecraft inspired, so I can gurantee some spooks and scares, but once you see them and get past them you'll be able to take it.
Up to a certain point before it becomes unnerving again. As stated, it's quite short, so it's perfect for busy players like you.
The second, 'I Wanna Be The Guy'http://www.bigdownload.com/games/i-wanna-be-the-guy/pc/i-wanna-be-the-guy-full-game/This game is pure sadism. It was made in 2007 (so I think you may have heard of this one), paying tributes to most of the platforming games made in history. It seems innocent enough, but you'll quickly realise how insane it really is.
It's also quite short, so you can beat it in 20 minutes... if you're a master. In reality, it'll take you over a few months to finish if you're busy, and you'll end with perhaps 2000+ deaths (Your death count displays when you load). Don't worry though, we don't blame you, it's hard. It was meant to be. In fact there's only medium, hard, very hard, and impossible, with the only differences being in the number of save points. Hard is the default difficulty.
Medium gives you more, but the extra save points are labelled 'wuss'. Surely you aren't one, right?
Impossible has NO save points. It's been done (see youtube for proof), perhaps you can be the next?
Hope you enjoy both games! Note that I'm not sure how safe the downloads are, so you may want to find other sources you trust if you don't feel comfortable.
