Shift 3 is a puzzle platformer where you can shift through floors, reversing gravity. It's a decent idea, and decently implemented. But the ending penalizes me for not seeking out every single secret in the game. In Seiklus and Knytt Stories, I didn't mind this because it gave me an excuse to go explore more. Shift 3 wasn't as good as either of those games. And the solutions to puzzles like the one pictured below seemed more tedious than intriguing.
So in the end the author made me feel penalized for not boring myself by wasting a lot of time hunting down clues. So even if I win, I end up with an unpleasant experience. Oh well.
