Thanks! I don't know if I am going to improve that concept, I work on other game right now (one with borderline the same artstyle).
For the 'interesting' part, I think I need to rethink the logo (I've done 3 already, but it really don't sell it). It just sad that we cannot put trailer on the submission page (only show up on mouse over). My work usually sell more if you see it in action lol :)
