I haven't gotten too far (almost cleared everything before the 2nd respawning rock) but I like what they have going on here, the interplay between various resources and stats is interesting.
If I were rating purely based on the current state of the game, I'd probably rate it 3 and "don't rec" because of how unnecessarily cryptic some of the game is.
HOWEVER: there's already a lot of good feedback on the comments, and having played this for a few days, even though there's no release notes I always check the bottom of the page to see when it was last updated, and the dev is working on it extremely frequently. (at time of writing this, it reads "Updated 5 hours ago")
The dev seems very competent both in their responses and in this game's overall design. Definitely worth keeping an eye on this even if you don't play it now.
