I really like this...
I can see you guys really put a lot of effort into this game. The music is excelent, It helps to keep the mood in the game, the atmosphere Its quite magnificent. The concept is verry good aswell, but could be a lot better. For example, you could develop a hole world of objects for the plataforms rather than rectangular boxes.
There is also a bit of hiden messages behind the kid obstacles...something intresting aswell...
Great game!
Keep up the good work.
