Wow. That's a great game. Yknow, while I was playing I was making mental notes as to what I'd write in this comment. When I got the ice part of the hourglass, I thought the only way to teleport was to go to fixed stations, and I was going to write "Seems like a great idea, but it'd be better if you could teleport whenever you wanted". And then I got the other part of the hourglass, and suddenly I was playing "Effect and Cause" from Titanfall 2 (one of the best levels imo) mixed with Outer Wilds. I absolutely love that. If there's ever a version that's a bit smoother in terms of platforming, do let me know, I'll gladly play that game again
