Time Frame for this game was 1 day, I had challenged myself to create a game with as little as code that I could manage.
The main idea is very simple, drag the red dot block your finger, hit the black blocks to destroy them and keep the circle protected.
It was a simple idea and only took less tahn 140 lines on code in the main Game state to create the game.
In terms of costing it was zero - I just created one red squre, one black square and a circle. Simple !
