Thanks for the in depth response!
This game was surprisingly time consuming to make, around 100 hours all in (which when also having to deal with work, life and a toddler, was basically every free minute I had), and stuff still didn't make the final cut unfortunately.
The biggest one was a bulkier tutorial, and another was more time balancing the loot / crafting numbers and enemy / player strength as I only had a couple hours of play testing the full game loop to try to tone things down a bit.
I am considering making a post-compo v2 with the full tutorial, the gem skills being more limited, and an end game challenge mode.
