HUUUUUGE THANKS!!
I really enjoyed reading your post, it's very heartwarming
Unfortunately, the benches aren't working anywhere except Cherry Bar, but I plan to add the ability to sit on them soon
Most of bugs and errors are fixed, that was also really helpful!!
Red screen and static appears when Aitsuki sees something traumatizing/nostalgic in her dreams, that's it
White-haired npc is Hamigaki San (Toothpaste), I'm planning to add something special with her
Also lamp effect (Candle) exists, it is located in Rosehip Garden, but the way to get to its dedicated is a bit unintentional, sorry..

I won't reveal some plot details, buuuuut i will say that some of the guesses are quite true
Also, here are the location names:
Yellow flower world - Golden Resin World
Train stop - Railroad Forest
Resting train - Orange Railroad Crossing
Starry garden - Illusion World
Neon sign alley - Greasy Town
B&W city - Noir Walk
Soap bubble - Foam World
Underwater Corals - Coral Reef
Oceanview city - Hometown
Marine Neon Party - Bioluminiscent Ocean
Metalworks - Copper World
Blood Sewers - Love Drains
Desert - Crimson Dunes
TV Channel - Milky Red Trails
Pink lake - Discomfort Bath
Dirty Laundry apt - Love Complex
And yeah.. You can't go through those trees in -30.. sorry
Thanks again for the review!! I liked your ideas and I'll try to implement them in future updates <3
