Gems you might have missed: Eversion

I recently got a chance to play a game that really managed to snare me. It was one of those things where I knew I had other, more important things to do, but I just couldn't pull myself away from it. I had to completely finish it before I could let myself do anything else. Few games can really do that to me nowadays.
I am referring to Eversion, a small freeware platformer that can be downloaded here. A friend suggested it, and I watched a short clip and wasn't impressed. It looked like a generic freeware platformer from the little bit I saw. Jump on enemies to kill them, collect gems (240 across 7 levels. You need to collect them all to see the true ending). The storyline seemed basic, the goal was just to rescue a princess. But let's just say...things are not what they seem. That's really about all I can say without treading into spoilers. It's worth digging a little bit deeper in order to see what's really going on.
Eversion kinda brought out some of the same feelings I got when I played Braid. There's no time manipulation, but both games give you a sense of being in a world where something is just...off. And I don't mean that in a bad way, it pulls you in and makes you want to solve the mystery, to figure out "Why are things like this?" The final resolution doesn't spell out everything for you, and I tend to prefer more concrete endings, but I walked away from the game feeling that it was worth it. It's a small download and should be able to run on just about any computer. Give it a shot, if you haven't already.
Just be sure to heed the warning on the opening screen.
