Great game! Good mechanics with smooth movements, I love the cooperative mode too.  A small suggestion, in the cave, while escaping from the collapsing rocks, I think it would be more appropriate for the environment of the game to use something like blade traps on the floor rather than balls in movement. I will love to play the full version so hopefully it goes out soon. Nice work :)!

Personal Note: I am an English-Spanish translator, in case you want an Spanish ver. contact me, If you keep the game free, I'll do it for free, if not, I'll do it for a small few.
