Perfect! 5 minutes of fun! Brings much joy :)
Graphics - 10/10 - I love the way you made the levels dynamic and different each time.
Sounds - 10/10 - Simple and sophisticated.
Story - 10/10 - Again simple, but as dankyy said, its an awesome way to describe your story in 5 seconds. Most people will only stop by for that long, lol.
Interactivity - 10/10 - Editable physics! Brilliant. Loved it.
Overall - 10/10 - You nailed it! Now all you need is a way to keep a database of the highscores and you can just keep making future variations of the same game system. Can't wait to see more from you :)
