Sorry about not updating in a few days, guys, I've been really busy and just didn't have time.
Super Meat Boy is another difficult playformer. It has a fairly simple plot, which is something along the lines of "An evil fetus in a space suit kidnapped Meat Boy's girlfriend, who's called Bandage Girl! Beat difficult levels to save her!" There are a lot of levels; about 200. The soundtracks are actually pretty well-made, and though this isn't a graphics-intensive game, there are a few different backgrounds you'll see throughout the game. So, how about the puzzles themselves? Well, the entire game isn't just "execute these difficult maneuvers consecutively and get frustrated," because that would suck (Hi, last level of The Cotton Alley. What were the devs THINKING?). A lot of the game is figuring out the best possible strategies for each stage. There are different worlds which all have levels in them. If you beat a certain time requirement on a level, you unlock another, harder version of that level. There are also different secrets in each world, such as "warp zones," which warp you to areas referencing other video games (good luck with the IWBTG warp zone, it's up there with the difficult bits of IWBTG itself), bandages you can collect, and intentionally glitched levels that are stupidly difficult to beat. The game keeps track of your progress with a nice little death counter and a percentage that keeps track of how much of the game you've beaten. Remember the warp zones I mentioned earlier? Some of those have characters that you can unlock by beating them, and some bandages will be impossible to get without certain characters. This is a great game, and I recommend it.
