Wow, that's crazy! They used the same asset pack for music, and one of the same asset packs for sound effects (the one from artisticdude) that I used. As far as I know, those asset packs aren't related in any way, except both being available on opengameart.org. I guess it's a small world when you're only considering CC0 assets. :-)
I played the game a little. It's a nice mix of classic roguelike, but adding some nice graphics and animations. Pretty cool! I'll try to check it out more later.
Thanks for sharing!
