Oh, to be a tourist double-jumping past security in South America.
This was interesting! Unfortunately my laptop is a hunk of junk and that messed with my experience a little (UE pinged me twice about unsupported drivers, lack of mouse sensitivity options threw me off a bit, and the controls are a bit floaty) but I still managed the platforming just fine.
Have listened to the soundtrack both in-game and on bandcamp and love it! Think it'd work well with some ambient noise to vary things up. In terms of level design... yeah, unfortunately it felt more like a game of "spot the level end trigger" instead of "lost in the backrooms". The entrance's design is quite distinct and there's nothing else like it, which makes it useful for navigation. But it also removes a bit of the horror and mystery, if... that makes sense.
It's also tricky to have a moment of "was that there before?" if new hallways are too out of the established path. Maybe move them a bit closer, or turn a light on (so players can see new stuff easier by turning the flashlight off?)
Don't really know how far in I got, unfortunately. Might give it another shot tomorrow and see if I can puzzle it all out. Nevertheless - a solid start, and good luck with the rest of development!
