Oh wow thanks for all the feedback! I definitely agree about the part in the beginning! I'll just make the answers not kick you back, haha. I agree about the issue with the effect, but that's actually a core part of the game!
Hmm. I see what you're saying about the dizziness. Ideally I would like the player to be able to beat the game in one sitting in ~2 hours. Do you think right now it's too hard to do that (because of difficulty or dizziness)?
The story is definitely a little bit too subtle right now. The child is actually mentioned at the end of levels 1 and 2 as the child who got kidnapped! He matches the description, but it does make sense that it's hard to tell given that nobody is going to focus on the jump scare, haha. Later in the game, the dialogue should hopefully make it a little bit more clear.
