Look at the italics . . .
The main problem with the game is that they did not take enough time to truly develop it. The gameplay is too easy, except that the jumping is not very reactive. The game only takes about 30 minutes to finish, which is way way too short for any game. There is no variation in the gameplay except in the combination of routes you can take (but they are all too short).
If you can't see the theme of this game, you may want to remind yourself that it is the opposite of long and good . . . TOO SHORT!!
