This game had great potential, and I really liked the idea, but I ended up disliking the game as I progressed. It seems like at later levels they stopped focusing on the puzzle aspect of the game, and started to focus on platforming and skill jumps instead. To me, once you understand how to beat a level in a puzzle game, it should take a couple of tries max to beat the level. This is best seen in Portal. Some of you probably think its not fair to compare the two games, but in reality they have very similar concepts. In Vitrum, however, I often found myself extremely frustrated at my inability to complete a level that I knew how to beat. Don't get me wrong, I like platforming just as much as the next guy, but this game takes it too far for my tastes. Almost every level includes some sort of difficult jump that made it difficult to beat. This is the type of stuff that I would liked to have known before buying it. If you like platforming, then go ahead and buy it, If not, stay away.
