I'm currently doing my first play-through of the game. It's wonderful and I love the poetry in it... It also seems like it is short, thus being a great game for speedrunning !
Even though most of the game is filled with invisible walls and that you're not free, I'm sure we'll find some interesting tricks.
I've already found a huge glitch with the pillar which skips 4 minutes in Chapter 2. I'm going to upload it as soon as possible.
Anyone interested in this game ?
