It was fine, but the game play was very repetitive.
Recommendations:
- There should have been more juice. For example, visual and sound effects for hitting the bits of paper.
- Maybe, instead of static bits of paper, how about hitting drones flying around the screen, one of which has the code? Then the drones could explode when being hit.
- Improved colour palette. Have some sprite as the background image instead of leaving it as a plain colour.
