The aesthetics were the standout here. The level design and AI citadel feel was very nice.
The sound design was quite calming, I liked it, but didn't feel any sort of horror or even urgency. I feel like having a clock to race against or even making it a best time sort of thing would give it more replayability and exercise what is actually a really nice and fluid parkour system! I would have loved a level with a more open feel so i could have really opened up and sped through using the parkour mechanics.
Overall The best parts here is the aesthetics and the movement mechanics!
Good job!
