Yes, Very much so! There were only a few pieces where I felt the dialogue could be changed up just a bit to be maybe a little more dramatic and unsettling, but the things i REALLY enjoyed was the "the pain... so hot..." usage, and just the all around great tie-ins that MAKE SENSE unlike some mods that I've played that totally ignore the main story that made CS so great. Though the idea of King's house opening up struck me as odd, it's somewhat believable that it could be patched up later on. I'm wondering though, how King's house will wind up looking how it does in the original CS game.
One more thing that I must tip my hat off to you for. The style of additional music in the game is very fitting and cohesive with the OST, so it doesnt feel like you're stepping out of Cave Story when it comes on. That's what i probably enjoyed most, but then Video Game Music is about 80% of any game to me, because 80% of the game is coming back to it years later and bursting at the seems with nostalgia
I'm hoping that you'll continue your work on it, it's turning out to be a really promising mod 8D
