Hard to rate this one. Easy to understand and play.
However, I would have liked to see how much further the author could have pushed it given submission was 6 days before deadline.
I don't put much effort at programming so I made this game it was too easy and I was like how I made the game in just 15min so I waited for a while to submit the project so that no one will think that the game is made in 15 min!
