@ k00l.cat  Thanks for your suggestions,  I tried to make a small engine and the same time of making the game for the jam so in the end, I couldn´t finish all the planned features. My bad!

Beautiful game, but somewhat empty.  Here are some suggestions: 

• Make the environment more interactive, let players interact with cat, as beside feeding and cleaning it up, you're just staring at the cat.
• Another suggestion would be to make cat more animated, to make it feel alive.

All in all, beautiful art and music, but a bit lacking in gameplay, even for a tamagotchi.
