This was a sweet entry. I love the minimalism of the theme: cubes making eggs... and pooping all over the place. It is really comfy, charming, and dragging the food/eggs into the creatures and the chamber is really satisfying, that *pop* effect is delightful.
Starting with the primary colors and eventually making the others 9 (12 total) is a good concept for a tamagotchi-like, since first game had exactly 12 evolution too! I am expecting to play your promised finished version soon (I'm also making a 1.0 version of Moonmon until the showcase).
*I just opened the game on the other tab and realize you can rotate the camera with the right mouse button, cool!
