Great game with some drawbacks

The game is very nice but there are at least three problems. The first one is that the game is low-res and nowadays it is not acceptable. Furthermore its width is not large enough to fill the iPhone 5S screen. Second, the linking with Episode 2 does not work on iOS 9 IPhone 5S and then I cannot unlock exclusive levels. Third, game controls are odd, it should be sufficient to tap everywhere on the screen to jump! My evaluation will increase if some or all of these comments will be addressed in a future release.
