First off, thanks so much for your feedback!
We do have a lot of plans for the system, firstly there are already axes, warhammers and spears waiting to be added but an additional system is needed for the hafting. Are there any specific type of more unusual swords you were wanting to see? Or any other weapons in general?
At the moment the temperature of the sword effects the amount of change that each strike has. We do need something else too though such as click and hold or perhaps the option to do a stronger strike.
The plans for the game it would be part of are still in development and somewhat secret at the moment, but we would have ways to make the investment in forging quality weapons worth the time investment.
Thanks again for your engagement, it's super encouraging the someone taken the time to play our little feature demo!
