Impressive!
Most of what I would say has been said by other commenters already.
The only thing I'll add is that I missed an overarching goal, a motif, a "fantasy".
For example, I built the Axe and Pickaxe hoping they'd change gameplay in some way, but no.
I waited for difficulty to pick up, perhaps harder items in less time, but no.
One can simply labour and toil mindlessly, without a strategy to "beat the game".
Please take that criticism as a token of my investment, I really liked what is there already.
