I was noticing that Reflexive (Creators of Wik for the XBLA) have been uploading some games to Kongregate.

Acutually I was just loading up a game, and noticed the reflexive logo in the intro to a game, then realized that reflexive had uploaded a few games.

The one I played last night was "Dr. Membrane - Sliderama"

I don't really see this translating to the XBLA too well, but it is a very well-designed puzzle game.

It plays like a sliding puzzle game, but not with pieces trapped in a grid. Each level has a unique layout on which you can slide peices around.

The goal of each level is to get specific peices into specific locations. What makes it challenging is that moving one piece tends to move the others.

If you try the game, you can click reflexive's name at the bottom of the page to see the other games they've uploaded to Kongregate.

Play Sliderama.
