A very nice and short psuedo-metroidvania. You gain abilities and can come back to get stuff you missed, as is par for the course, but there is essentially only one path that you are heavily recommended to follow, lest you stop making headway. Main concept is fun, a paint the world type gimmick. It took me maybe three hours to beat 100%. Definitely worth the 5 bucks, but if you can get it on sale, even better.
