This was pretty unsettling, tense, and punishing-- the music and odd arrangements of items definitely set the mood for me, and I found myself rushing around to find the keys and lightswitches as fast as possible. I would have liked it if the keys had some kind of pickup effect, like the switches-- I was confused in the first room the first time and wasted a good chunk of the power I had left, and wasted some time on the next run too when I didn't realize there were multiple keys and went back and forth trying to pick it up again. Regardless, making something functional in 48 hours is a feat, so keep it up!
I really hate to be That Guy who just comes in and savages something, because I know how much it hurts, but, unfortunately...I've gotta be That Guy.
Firstly. The music. Oh my, the music. I know how crazy tricky it is to make something that sounds good, but...just pressing random keys piped into FL Keys isn't even close.
Then there's the movement system. Something about it just...doesn't work. It's simultaneously too sticky, and not sticky enough; in the difficult terrain you've built, the player controller you've got *really* doesn't work out. It's too hard to parkour, too hard to even just get where you're going.
Then there's the lack of feedback; the simplest sound can do wonders for adding feedback to actions. A little bling made in BFXR or something of the sorts for activating keys, a tick for flipping lightswitches. It'd make it so much better.
Finally, your power loss is WAY too punishing for the difficulty of finding lightswitches. I was barely able to make it three rooms in before throwing in the towel because I simply was unable to find power switches fast enough.
The idea could work with tons of polish, and some stuff being cut or rebuilt, but as it stands right now...it's pretty bad.
The best hellish art gallery I've seen before! In all seriousness though the lack of player feedback when you activate keys is an issue, and the music is painful to listen to. That said I did like exploring the crazy geometry and with some simple changes the game could become much more playable. With many changes outright great.
