Senseless puzzles. It was more like guessing than logic. The implementation is very fine but the story is crap. Please try again with another game and improve the puzzles and the story. There should be a way of imagning what to do next. I had a hard time solving this game even WITH the walkthrough.
At a certain point you cannot change guns anymore and the cash you earn is not added to your shop balance. This could be a quite nice game if these features worked. Please repair that!
I think the game is too easy. It seems there are twice as much platforms as in the first part and not hitting them is very difficult, too. It took me 5 minutes to come back down again after I reached the 100,000,000 ft mark. Though I love this game :)
...seems to be a bit buggy, though. Game didn´t continue when I took out the metal rod again. Also my shovel disappeared when I wanted to pick up the exotic plant.
