A nice mouse-based game that strikes a decent balance between difficulty. There is sufficient feedback when you successfully hit a target which is good.
However, there are a couple of issues. Firstly the game is a bit tricky to boot up, consider exporting the game properly to improve ease of access. Secondly, since the game starts instantly you are more than likely going to lose a few points in the beginning. Thirdly is that there could have been some feedback for missing a clown as well. Finally, perhaps making the game more difficult the higher the score you get would make the game feel more challenging over time. In addition, is this really a Single Control Game? Mouse moving and clicking would be two separate inputs, no?
All that aside, you have handed it in a day early and clearly attempted to meet the requirements set during the lecture. Good work.
