One small piece of feedback that I remembered, but I think it would be cool if you could use Caestus skills while weaponless, since that logically makes sense to me and would also make my hypothetical fists-only playthrough more interesting. I do know that working with NULL weapon can be a pain though, and also that that might take a little bit away from the powerlessness of lacking equipment, so it's alright if it doesn't happen.
I'm glad to be of assistance with the errors and also glad that the combat will be more fleshed out in due time. I will be sure to check back every once in a while to see how this is going! Thanks for the downloadable version as well.
