Just to briefly add an additional opinion to this discussion... For me, the RNG mechanics were never really questionable. They achieve what they set out to accomplish very well, and it clicked for me almost immediately.
There is no shortage of games that cater to maximizing fun and pure engagement & progress. This game seeks to be something different. It would seem that this game could be described as, among many other things, an experiment to test how the removal of some quality-of-life features typical of adventure games and rpgs can emulate a particular experience and induce a specific mood and state of mind in the player.
Not all experiments succeed, of course, and in this case success can hardly be measured empirically, but for me this works perfectly, and only seems to be getting better as the dev tweaks and iterates on the concept.
As has been said, this game does an excellent job of synthesizing aspects of Samsara as the concept has been interpreted in different ways by various Eastern strains of thought. It succeeds in transposing this synthesis into an experience for the player. This was probably difficult for the dev to conceptualize, and the transposition was probably even more of a challenge. It would be a shame for that to be left on the table.
Obviously this is not going to click for everyone. But it is much better for that. This game, even in its current state, leaps well above the lowest common denominator. It's very special and I want the dev to know that there are many people who appreciate what they are creating here. Can't wait for the release, I know many many people who will be interested in playing this.
