Honestly - great showing! It has the nugget of fun that just needs some polish to make it addicting!
A few suggestions since you asked for them
1) Find background music thats a bit longer, there are lots of free stock music you can use as long as you credit the creator :)
2) Pause the gameplay when the shop is open
3) Get the eggs to spin a bit when falling
4) Have a few egg collection sounds to cycle between to keep it interesting
Awesome game, you should be really proud! I'm excited to see more of your work in the future
