Hello Dasius! I've been playing this for a month now, and I thought that this was an amazing game! I'd like to suggest some things.
1. Magical Weapons
Yeah, I'm suggesting fantasy-like mechanics. But we do have magical crystals. Once you level up, There is Magic Option other than Charisma, Agility, Strength, and Intelligence. It will be easy if every level up gives 5 points, like in IGP's new video.
How It Works
Once you forge a weapon head, you take it to a Magical Desk and fuse your magic with the weapon. You either fuse Fire, Water, Earth, or Wind Magic into it. Then you can take it to the Crafting Table.
If you sell a magical weapon, they give magical currency ( eg. Cursed Copper or Spiritual Silver) that you can use to buy items for your Shop. ( ex. Magical Earth Tin Great Hammer )
New things I mentioned :
Magical Weapons
Magic Level
Magical Desk
Elemental Powers
Magical Currency
Magic Items ( Like Magic One Hand Grips)
Edit : This might be stupid of me, so it's your choice if you want to do it.
I might think about other ideas. (Hmmm....... What about mini-games?)
