This has to be the most challenging platform game I’ve ever played; Super Meat Boy (SMB) rises steadily in difficulty from easy to ridiculously hard core crazy. After passing the first boss I had to stop simply because my tired old bones and aching hands were almost suffering from RSI . That said; this is a beautifully executed game that will keep the most dedicated of platformer fans wanting more.
SMB has an endearing style of its own (despite the copious trails and splashes of blood with precisely designed levels that fit the theme of the game perfectly, plus it takes me back to the days when skill was the most important attribute for getting through a level. You'll need lots of that if you are to get to the end of this game, especially unscathed. I really don't know how anyone could get through a complete area without dying at least once. You'd need to be superhuman, or one of the best platformers in the world to beat these levels.
You'll often be surprised or even relieved at how short some of the levels are (no more than about 30 seconds); that said, with a content of over 300 maps, bonus stages and hidden warp zones that contain challenging extra-maps, dark worlds (one for each stage, e.g. Salt Factory Dark World, Hell Dark World etc) and, not forgetting the unlock-able characters which can be gained by collecting bandages that are placed in hard to get locations on several levels or finishing warp zones - try getting through one of the main stages or the hidden dark worlds without dying to gain achievements - only 0.6% to 1% of the Meat boy community are getting these achievements because they are ultra hard to achieve. Anyway, with all of these extra's plus using the editor, (which you'll find in your library under tools), you have the potential to create unlimited levels, that are only limited by your imagination, need for more levels and stamina, it's hard to get bored of this game. On top of that you're able to implement Maps made by the community.
If you don't already own SMB; now that its over 3 years old, you'll easily pick it up for a bargain price, especially in the many Steam sales that we get these days.
I highly recommend this game, despite me not achieving much in the way of completing most of the levels yet , (I've spent over 20 hours playing this game already and I'm still hungry for more) nor getting many of the in game achievements (couldn't be bothered collecting the bandages, lol). I certainly intend returning to the game when my hands have recovered from the deviously executed level designs.
If you've not played this game get it as soon as you can; maybe check out the demo (unfortunately Steam don't offer a demo download), or play the browser based flash game:http://www.kongregate.com/games/edmund/meat-boy
to get a feel for the game.
Highly recommended and a 9 out of 10 from me (it loses a point simply because its a little too hard for me.
Last words: It's one of the best platformers of the last decade in my opinion (apart from maybe Gish).
