Seems like indie platformers are a dime a dozen, and indie platformers "with a unique twist" are even more common. Eversion is an indie platformer with a unique twist. Initially evoking nostalgic memories of the likes of Super Mario World, Eversion quickly takes a dark turn to the strange and twisted. The gimmick, here, is that you can use a special ability to "evert" into alternate dimensions -- essentially different versions of the same level with different graphical styles, background music, enemies, and hazards. Navigating to the end of the level and collecting all of the gems along the way requires clever use of the different dimensions.
Eversion is pretty short; it only took me about 45 minutes to reach the ending, despite spending a lot of time dying and replaying segments of each level. Despite being so simple, the game sometimes reaches levels of "Nintendo hard" that had me dying repeatedly because of stiff controls and unpredictable hazards that required me to die, learn the hazards, and memorize the layout in advance. Using the everse function to navigate the maps is a decent idea, but it's a little annoying when you know you have to evert but can't find the right spot in the level to do so.
I wasn't terribly impressed with Eversion. Indie platformers have to be really special to stand out in my eyes, and Eversion seemed kind of average. When I reached the end, I was happy to be finished with it and didn't have any desire to go back collecting gems for extra secrets. If you're curious to give it a go, you can download it for free on the official site, or you can buy the upgraded HD version on Steam for $4.99 or as part of Kyttaro Games' current Bundle in a Box (pay what you want, minimum price of $0.99).
