Leaning on the weaker end of Portal mods, this game still provides a cute little experience centered around a very fun & new mechanic. The puzzles feel mostly in line with the franchise; however, I personally would have liked to see the parkour aspects of the paint gun more utilized. The writing is... certainly there. I found some of the dialogue cute, but most of it ended up falling flat for me. Mainly, the main core, Nigel, he's a fun character but just maybe not as colorful as the cores you'll find in other portal games, fan or official. Overall it's a very lovable experience; however, for the $5 price tag, I think you'll find more enjoyment out of "Tag: The Power of Paint"—the free title that inspired both this game as well as Portal 2's gel mechanics.
