At first moment I was thrilled, but then I found out how big the map is and how much time takes to get to the "yellow point" which is most probably just a food. This game lacks huge balancing and polishing. The map is huge and there is absolute no reward for going through whole map (for yellow dots).
But still ... it's a good game, good idea. Try to polish it, balance it, give it better "reward system" and it will be glorious :)
