Hello I just got done with the demo so I'll proceed to write my thoughts here in the comments about the experience. I will preface that in all my years of gaming I barely if ever touched a visual novel style game. So this feedback is from the perspective of someone who isn't usually interested in visual novel games. So here it goes.
The game is captivating right from the start. I really like the atmosphere as soon as you find yourself in the menu of the game. The idea of the game is interesting and I can see I could get easily immersed in this game in particular. The whole premise of the game is interesting. The white void the mysterious voice the paintings that appear are all really intriguing and it makes you want to find out more about what is going on. Safe to say the game hooks your interest right from the beginning.
As far as issues go I haven't really seen anything major other than some spelling and grammar mistakes here and there.
Another thing I noticed is that when you click to continue with the dialogue the murmurs/whispers that you hear in the background get cutoff and it really takes you out of the experience. The whispers should perhaps be constant or at least be more subtle so you don't notice them getting cutoff while going through the dialogue.
Another thing is in the ending that I got with the screen getting all red and a weird creature keeps appearing in the reflection of the main character, that part really took away from the horror atmosphere and it felt almost cheesy as if it was trying too hard to be scary. I would really lean into the more subtle horror of this game with weird sounds and cool scary ambient and I would leave aside those type of sections where things get really loud and things start flashing red. I'll probably try to get the other endings as well and see what other things this demo has in store. Overall I enjoyed this short demo. I really love the concept of the game and I never thought I could enjoy and sit through a visual novel type game. Really excited to see more of this game. Good luck!
