This is great; I love it. I have no idea how anyone can possibly create such a polished game in such a short amount of time!
Clearly there's a lot of talent and dedication involved.
As the source is available, I like to have a poke around, to see if I can pick up any useful coding and game organisation tips. I noticed that the event in your scene-selection level is huge, and as I am an optimisation freak, I had a go at compacting it to around half a dozen blocks, down from around 50. I appreciate that optimisation is not at the forefront of one's mind whilst developing to an extraordinarily tight deadline, but I hope this will be useful to someone.
I have attached a screenshot of the original event, and also one showing my replacement code.
I have given it a quick test, and it seems to work fine. I would add that my code achieves nothing new, and optimization isn't particularly important here (it's not going to affect game-play), but I was thinking that it saves having to add or remove a set of blocks each time a level is added or removed from the game. This is the part of coding that I find tedious and error-prone, so I try to make life easy for my future self!
