Hey, gave it try here's what I think!
I liked the physics simulation, unusual to see that in an incremental game and I think that's neat! However, sometimes the ore would get stuck or take too long to move despite high conveyor belt speed, I think that making it a bit less realistic but more stable could've been simply more pleasant to deal with since the player doesn't expect the simulation aspect to actually affect their progress, but it was a very minor issue.
The subtle hints at the goal and what you can do with the water gun are cool, but it would be better if there was a short introduction of sorts also. I do like how souls function as passive upgrades and need one of the bots to be sacrificed. It was a bit weird how there was a "starting" bot you couldn't sacrifice, I understand that this was there to prevent players from losing all bots but I think just not allowing the last bot from any category to be sacrificed would've been more elegant.
Overall it was a pleasant experience, trying to max up all the upgrades and get to the diamond! I also do like the visuals and the cozy cavern a lot
