Ensure that your submission title has your student number on it. A very visually appealing game, with a great soundtrack, and responsive controls. Given the time you had, this is incredibly impressive. I was determined to play the game entirely and was engaged whilst doing so.
Is the way you have exported the game the most efficient and user friendly way possible, are there alternative methods that you could have utilised instead? Secondly, I found that the spikes were a bit difficult to track at times and were a bit tricky to see. Finally, in the third environment you could clip through the ceiling and walk over some of the obstacles, was this intentional? it didn't look like it should have.
With some tweaks and more levels, this would be at a level which could be put on a marketplace, and something that I could see myself playing on the train or whilst waiting for a bus. The transitional "you unlocked xxx" is a nice touch that adds a level of polish. The game feels really nice to play, not to difficult but not incredibly easy. Great work!
