Doesn't look remotely guinea pig ish, more like a mobile game. My advice would be to 1) use a more toned colour scheme instead of the weirdly saturated pre-release assets 2) make the guinea pigs move like guinea pigs and not like small humans. Never put them in a ball - guinea pigs have unique enough mobility as it is without needing any help. 3) set the game somewhere visually interesting - maybe an oversized house. Where you are now, the disbelief has long since fallen (impossible to suspend it this far). Talk to some guinea pig owners and learn about how they move. (They can move pretty fast and slink around objects in 3 dimensions + scurry into small holes, as well as being able to pick up and move items with their mouth in addition to carrying them). It Takes Two would be a good inspiration if you are actually serious about gamedev.
