Hi, saw your game after looking up coding stuff on YT, thanks for that! Playing the demo now, and have some thoughts.
1. Some of the menu is a bit broken. For example, if you're on the Enhancing Skill page, close it, and then try to open the brand sheet, you get a broken menu. Additionally, if you're in the brand sheet, close it, then try to open the character sheet, it opens the brand sheet. C should always give you the Character Sheet, B should always give the Brand sheet. Similarly, B and C both close whatever left-side window you have instead of opening straight to the page, i.e. if I'm in the character sheet and I hit B, it should open the Brand sheet instead of closing the character sheet.
2. I have a Rare Hammer at level 3 and have no way to use it, none of the skills take hammers this early.
3. In related issue, you cannot see what weapons a skill can be used with until you purchase it. I'd rather see that in the buy brand screen.
4. Abilities should recast if I'm holding down the key, I don't want to be spamming my click/key constantly. Same with the left-click move.
5. Left-click move should be able to be disabled as well, it's a bit odd having WASD and click move on at the same time, personally.
6. Ranged skills seem to have trouble coming out at all in 1 tile wide hallways.
All in all, looks promising, but the QoL things definitely start getting in the way pretty quickly. Design-wise, I like a lot of what's going on.
