This is a really well polished and smooth parkour game! I especially love the red gravity switching bits although it's not always clear which way is the originally down direction which was relevant in the octagon finale.
I felt so clever when I was able to skip parts of the level like one of the sticky wall by just jumping down and skipping some jumping puzzles by cutting corners (literally). I was also able to run back to a previous room before the gate slams shut and soft-lock myself. It would be really funny if the announcer acknowledge that.
Speaking of announcers, the voice over are well written and well made. I appreciates the bits of jokes and puns you've put in. They really made the game world felt a lot bigger than just the gameplay. Good job!
