A simple hide and seek game where you have to 1st pass through some checkpoints before beeing able to exit the level.
It has 12 levels and they arent very hard. You just have to evade the guard accordingly, which takes some time to learn.
The levels on the startup of the game are all open, so even if you don't get to finish one, you can still go and play the other level. Another game with the same game layout as this one, that i reviewed yesterday or so had the same issue.
After unlocking the 2nd level, it may not unlock..
The achievements are easily achievable since every level is unlocked at the start of the game.(it relocks after playing a stage)

Edit: You have to reset to get the level lock/unlocking mechanism to work correctly i think.
