Does anyone know how long the full version lasts on average?

just saw the game then saw this one https://store.steampowered.com/app/3769130/Keep_on_Mining/ why so similar ?

How do you get access to level 6 Elementalite? I have all the artificats that I can possibly get as far as I can tell, (99 total), I'm at max level 145, maxed all the upgrades/nodes available, and there doesn't seem to be anything else to do. I completed the level 5 elementalite duality stage a 2nd time just to be sure, and I have done several standard runs after the fact just to see if I could find anything else but haven't gotten anything new in a while....

Hey, I have 100%ed the game a few days ago and the ingame achievement tracker reflects this, but the equivalent steam achievements are not unlocked. All of those are minor achievements, that would likely have been completed within the first hour of playing....

once you hit 145 (max), you still gain xp for some reason so when the round ends, it says you've leveled up like normal but you didn't
