Thank you very much! I was afraid I'd done the graphics a bit hastily. But in the end, looking back on it now, I'm really happy with the way it looks.
As for the music, it's pretty much what I had in mind, i.e. something catchy and progressive. To be quite honest, during the live session on Twitch, the chat members helped and advised me a lot during the creation of this music and it probably wouldn't have been as good without them :)
