I found a few bug keep in mind i was looking for them in an alpha.
1. if you stack heated ingots on the anvil atop one another one disappears and will remain there no matter how many weapons you craft.
2. If you save the game leave and come back any weapons you have stored up./ inventory will break apart and the metal will be heated again.
3 the crafting switch wheel don't always work.
4 the customers don't always spawn in when loading the game.
The last thing i tested was the mining in sand box it works great no crashes but if you plan on implementing it into the game you might want to make a cart of some sort and some other tools. you could make them part of the leveling system. and i saw a forestry area i look forward to making handles. also there is no way to make a center of a shield. i know they r a work in pregrees though. keep up the great work.
