This game has the idea of simulating a oldest japanese toy, but it has few things besides giving food to the animal, I'll give you a feedback:

Try to polish the game's graphics a little more and make them more standardized (I found them a little amateurish), add more options for the little animal to do, and also add something like suspense or horror.

I'm not a fan of FNAF fangames, but judging by the graphics, it might be a cool game. but I didn't find it very polishing

Feedback
Even though your game is more focused on PCs, try to adapt it to touchscreens as well.

The art is good, but I didn't understand anything in the game
