Don't know how early it is, but nothing much seemed to be happening. Even then, with the math problems on screen at all times, I couldn't really look at the pet.
Hey, thanks for the feedback. Yes, this is very, very early days (it's essentially a test to make sure it runs on all the family devices). I'll be adding small updates every few days as I only have a couple of hours to work on this each morning before work.
The "pet" is just a blob of light right now, but I will give the player options to convert energy into evolutionary upgrades. :)
