Sounds great, I enjoyed the previous streams too! Hopefully I'll be able to be there to watch it.
Nessy's mentioned the BGM; I recall you changing the ambient/atmposheric track to my Contest #14 entry and I quite liked your choice. This time, however, I don't expect you to mind my selection judging by what you told me on IRC some time ago. I love sharing music with others, it's a topic very dear to me especially since next to nobody I know IRL has similar tastes.
Still, I see no reason to prevent anybody from enjoying a level if they'd like a different BGM to go along with it.
If you do make a change, please don't hesitate to tell me why on IRC/here in the thread/in a PM! I want any and all feedback!
