I think this is a very creative game and a pretty neat idea. The game looks very good.
I think adding a curser for the paella throw would improve the game a lot since it gives a clear indication where the it will be thrown. Making the area bigger as you progress could be nice as well.
Also increase the Button collider of the main menu play button. And maybe add an enemy counter on the top ig. And have more power ups. And indicator for when you'll get a power up.
The music is pretty good and the voiceover is kinda funny and fits the game
Overall I think this is a great prototype and with some improvements and addition it can be a fairly nice game
