I did not inspect the code, but I did played it for a little. The most challenging part for me so far is to remember to periodically poke the mouse so screenlocker won't kick in.
I loved games like PQ and Godville back in the day. I hoped they'd be full games in themselves but sadly most remained comedy. It's telling how Melvor Idle really took off despite being so mediocre. There's a lot of demand for it.
