Some things I noticed right of the bat:

- I liked how you made things creative by using your choice of png's instead of unity packages. 

- you included mario shooting animation

- You kept track of the shots fired which I think is very unique

- I enjoyed the humor you provided with the goose background and the choice of apple and bomb png's.

- clear instructions. 

- pause button is in the middle of the screen where the gameplay is happening

- Free movement of mario makes hitting apples not challenging at all

- shooting a bomb restarts the level but my score does not get penalized. 

- default points of apple is 10 but do not change based on size.

- size of apple becomes too ridiculously large
