Such a cool game! I love the idea and the asynchronus gameplay is super neat. I didn't get too far into the game (only ever got the 2nd gem in the 2nd level) so a checkpoint system after each cristal might be nice. I am also wondering if there are some thing which only the low level character can do, because the big guy is too overpowered already (like he is skilled as a warrior and the noob can learn to cast a fireball or something. Either way I love how you made the experienced play explain the controls and generally told the story. This has so much charme to it and so much potential. Really well done!
