ofc, it's such a good game!!! as evidenced by my being so engrossed in it that it took me ages to realize I was missing a bunch of stuff XD like I'm already so impressed and having so much fun!!
1. I think it starts as soon as the game starts! But not everything is missing. Like for instance, there is the falling snow effect during the introduction, and there is the glitchy overlay during that one scene.
2. it does! I went a good while before realizing there was supposed to be sprites and backgrounds pfft
3. yes, there is! mostly part of the reason I became so engrossed to the point where I almost didn't notice TwT voice acting, effects, and music, it's all working perfectly!
4. Yes, I did T^T I've also tried reinstalling the game and restarting my PC as well and none of it seems to work.
5. I've put together some screenshots if you need visuals, as well as the last line I've made it in the game so far!
