Great concept, I loved everything I played. Puzzles were appropriately challenging, writing was fine, new mechanics were cool.

Unfortunately, after taking a break for the night and coming back, all saves I tried to load would result in a crash. I tried verifying my game files- no luck. I tried reinstalling the game and it wiped all of my save files. Portal: Revolution was a cool mod but with the frustrating experience I've had over the past couple of days, I'm not going to bother coming back.
