ok a lotta things to answer here so lets start
Ans 1: thanks for reporting that skybox level 9 bug, looks like it made it past my playtesting
Ans 2: that flashing face glitch could be a HTML problem if you were playing on HTML try out the downloadable version if you get time it should run a lot smoother
Ans 3: yea i was trying to add movable dead bodies in the game but halfway through the process i got occupied by something else and ended up forgetting about, dumbest decision in my life
Ans 4: yes auto generated music does not mean good, i know quality > quantity, but somwthing is better than nothing at least {insert_shrug_emoji_here}
Ans 5: idk, the idea seemed good to me so i was like "yea it would work" -me, june 2021
Ans 6: wait there are other games with this mechanic? i didnt know that, ah well what can i do
Anyways im glad you played it and left an honest review :D
