Pretty neat idea actually! It did crash for me during a level transition like you mentioned in the notes but I still enjoyed it! Music was good as well. I think this could be made into a full game. Overall, great job!
I'm still yet to figure out the exact cause for the crash, but it seems to be a pattern right now that new players experience the crash. I am still unsure if this is related to an engine bug I uncovered during development, or just some bad C++ I wrote in a hurry.
