I really love the idea of making a kaiju pet. :o
Sadly evolving seems to be broken for me. I could go far beyond 100% and nothing happend.
Only first 20% evole worked.
The music was good but not a perfect fit and I also liked the pixelart a lot, especially the info panels, although I think it would be better to stick to one strict pixelsize instead of mixing it up. It looks a little off having the pet and food in another size than the background/house/object.
Also the % numbers went out of the frame.
Volleyball was way to easy when you just stand in front of the net, jump and push a little left very late. You will win every time first shot.
