Finished
Just uploading my game for ld36 now 
Overall I like my game quite a lot. If I were to change something about it, it would be to have the levels in a more logical order, and with a consistently scaling difficulty, as right now the difficulty changes quite a lot.
This is the first Ludum Dare I have ever participated in, but it was quite fun and I look forward to (hopefully) doing more in the future.
