The game throws you into the world right from the start, and I assume it expects you to experiment, but at the same time, it punishes mistakes quite harshly.
You are technically immortal because after every frustrating death, you will always respawn at the top of the level, but the fact that any touch with the ground or trees sends you back to the beginning is somewhat irritating.
In all of this, I honestly miss a bit of world-building and UX finesse - practically every touch with the scenery will cost you a life, and the controls haven't really settled for me even after an hour of gameplay - so the result of this combination is quite a serious drag. The game also definitely lacks deeper settings because aside from resolution and keyboard/controller input selection, you have nothing else available - no sound options, vertical sync, key binding. There’s nothing.
Summa summarum - the game looks very good, but it's somewhat unfinished, cryptic, and tedious to play. With certain improvements, it could be an interesting Journey-type title - it's up to the dev team to polish what I would currently call a pretty good tech demo.
