I'm so sorry that my reply is horrifically slow >.< I have pretty much been out of it for all of December. I just got too overwhelmed with everything and couldn't cope with much, so as a result, I'm now crazy behind on my replies :(
Thanks so much for your kind words! So glad you had fun with the game :3
SPOILERS
Ah, man, that sucks about the gift >.< Unfortunately, I didn't actually make that myself. I made the main game with Naninovel, and someone else in the Spooktober team made Rhime's gift in Ren'Py. I tested the Windows version that she made and that works perfectly, but as always, I had no way of even opening the Mac one >.< and as far as I know, she doesn't have a Mac either, so she wouldn't have been able to test it :(
I could mention it to her, but since she can't test Mac stuff, I'm guessing she probably wouldn't be able to fix the Mac version >.< You're not missing out on tooooo much because it's basically just the extras section there as a separate download. It's got the OST in a music player, blooper reels, bonus art like sketches and other doodles from the different artists on the team, and my rambling about the project.
I guess I could maybe just upload all that stuff in a folder or something so it can just be downloaded directly from the gift page! Cos it's a shame if no one on Mac can see any of that bonus content >.< I probably won't have time to do it this year, but I'll make sure to get it all uploaded sometime in January!
Thanks so much for playing and I hope you get to have happy holidays :3
