Unity Game - Tropical

This game must involve combining code and 3D modelling for a tropical themed unity game. 

Idea 1: Player has to bounce beach ball on head without dropping it. More balls come down, see if you can catch them all. 

Turns out, I had no clue where to even start with this. New to Unity I thought I had to choose an idea even smaller than the one I already had. 

Idea 2: Ball must be rolled into holes on platform. 

The idea turned out okay. Instead of rolling into holes I made the player have to collect bananas and dodge umbrellas that would bounce the player back with force. Much like a pinball machine.

High Priority:
Beach Ball
Bananas
Umbrellas
Palm Trees (boundary)

Second Priority
Base
Water

Audio
Tropical theme music

After many problems, the game came out semi-working. 
Below is the finished snapshot.
