Thanks a lot for sharing the numbers.
Well. Any advertising wasn't any good for us ever. Almost (I had some tricks but this wasn't too well at the end anyway). But any additional exposure is good anyway. Because later it sums to some wider awareness about you and your company.
PS I liked your FB page. If you don't mind I have some comments on the game. I'm sure you've already got a lot of them so sorry if I'll repeat some:
- you need to highlight that your main hero above the background and flying blocks ( backgrounds are very beautiful and bright but the creature is just invisible on them ) - make some glowing around it, make it different in color and brightness;
- perhaps you can even make that backgrounds not so bright and colorful (use them in full brightness in some positive moments in the game);
- current flying blocks are just out of your visual style - they strange and dul ( sorry! ) - they should attract player ( and creature ) attention, look more bright and dangerous, and better appeal to visual style of backgrounds and main hero (wooden beams perhaps? );
- add more active motions for that your creature, right now it just hangs down and don't react on neither player inputs or obstacle flying around it - the main game heros don't act so

;
- if I assume correct you should drag that circle under your hero to move it? Why you need it? Why don't let the player just drag in any part of screen to move it? I think it would give more freedom in game contol and people like the freedom.
Hope this helps
