Very trippy puzzle game!
I did encounter a bug at 4:40 in my playthrough though. I am ascending the waterfall section and I 'think' I clip through the geometry because the game then locks up and I have to restart it.
However, it was fairly easy to get back to where I last was (speedrunner strats!) and the odd bug is expected with prototypes/alphas anyway.
Still, this would be very cool fleshed out into a full release!
