I love the way that the puzzle rewards are nonsensical (get the item by messing with the clocks), but the *solutions* are all things that follow logically from the clues.
Except for the things that trigger based on moving around.
Roughly three times as many missions as the content supports. And as of 1.2.2, the coin get sprite still conceals the player avatar, making survival mode simply a challenge to see if you can catch the health packs, because you can't see anything but coins and gems.
Suggest putting the coin and gem sprites behind all of the more important ones, rather than cover the enemies with the treasure.
Locations of the win spots are too predictable; I shouldn't be able to get three or four in a row almost instantly just by recognizing the pattern of 'it was here last time, so it should be here this time'.
Or should I?
