Its a fun little creature caretaking game. The fact that what you feed the dragon makes it change what it looks like is a really good addition. Its very easy to get stuck in a loop of not being able to feed the dragon unless you figure out the specific mechanics due to how mood works and the dragon not wanting food if it has low mood but that still decreasing the mood even on failure (e.g. at 22% mood).
The main things that would be able to be worked on post jam would be ux improvements. This is things like making the bars consistent in how they behave (either all filled = positive or all filled = negative) and making items consistent in how you use them or convey differences (currently some want to to hover and some want you to click but you dont know which is which and clicking for the hover ones does the same thing as the clicking for the clicking ones (aka making the item dissapear))
