Ok, so... I've been seeing others' sugestions, and yeah, while a slightly better jump and maybe being able to run would be nice, I honestly couldn't believe we couldn't slide on the, er, slides. My disappointment was immeasurable and my day was ruined (jk).
Now, let's see... Really like the premise, the fact we're just a dude stumbling in there due to our job, how the empty lots already look like those liminal images of hills and way-too-neatly-put-together houses, but without the houses (imagine if that's the ending, leaving the underground into a city that looks just like that, huh), the looks of the locations, how the fact so many of these rooms would serve no real purpose or just be completely out of place or built in a completely anomalous way in our regular reality... The fact you went out of your way to mention the water was warm was a nice touch.
The control panels were a neat little distraction, I do like how they look quite a bit, hopefully they get more complicated as you advance through the game... Those puzzles that did not include the control panels, but rather usage of the environment, either by interacting with it or through platforming, were great! I really would like that to be a constant throughout the remainder of the game, especially the former!
Lazy River was the first part that really got me, by that point I was already immersed into the whole ordeal... Took me quite a bit to find that big kiddie park, I was going cuckoo when walking down the path, in a good way!
The Reservoir and the Slides were the second parts with the most tension for me. Seeing how the floors interconnect, the seemingly meaningless rooms, the unnecessarily deep pool right below a hole on the ceiling, the rectangular vent under the water (which I was dreading having to get into, not gonna lie), the reservoirs themselves looking like regular indoors pools but with sunken walkways, divided by actual spa pools ...it makes the whole place almost make some sense, and yet it doesn't in the slightest! But then there's the signs advising not to dive, the jacuzzi, the look of the slides themselves... These look perfectly normal on their own, just absolutely out of place, and I love it!
The Locker Room was the most memorable bit to me. The eeriness of the surrounding darkness set the mood, the interactivity with all the faucets, lockers and showers, the dread of many rooms being similar, almost impossible to regularly navigate, the message on the mirror, the panic I started feeling as things started making noises behind me, it felt real! I was feeling a bit panicked, scrambling my way out of these now claustrophobic rooms and hallways of lockers and darkness! I didn't know what was chasing me, and I didn't want to! Genius idea to have Exit signs guide us, such a simple impulse done very well!
Amd as it turns out, it wasn't just a Spa! It was a complex of, possibly, many commodities, a mall even! Don't know what's an "In and Outlet", but I can't wait to see how they'll look like.
One last question... Will we ever get an explanation as to why this place exists, or how, or if it even does exist at all? Or will Anemoiapolis remain as one of those unexplainable mysteries of our reality?
