Wow, this is currently my favourite entry so far, there is just so much to talk about here in terms of game design.
Small things like the fact that the tutorial book which teaches you the shop, costs and sells for 20. That's a super elegant way of tutorialising it. You found an awesome way to implement crafting which really uses the theme of the jam very well, it is so cool that I can make different items with the same recipe, but different materials.
But one of the biggest MVP features was the fact that you can set the speed that battles take place. It is great to be able to blitz past the start after a while, even though the combat phase is nice and polished, the real meat of the game is in the forge phase.
Very polished entry with nice coherent graphics and soothing audio.
