No offense intended but I dont really see the relation to the theme
I think having a main menu would be good.
At first I didnt know exactly what to do but I figured out after ckicking that it was about matching fruits,I think you could make it so when we hover over the tooth,there is a highlight around it.
For the audio, some sfx when we match the fruits is necessary it feels rewarding and I think you forgot to make the main theme loopable.
Overall the game feels unpolished but I think with some more polish ,you can get something :)
