Very cool! I'd be really interested to see what your RPG does mechanically - how you resolve skill checks, etc. Making an RPG is no small feat!
Thanks!
I wanted to try making an RPG without dice. Instead (during combat) you program your actions into a timeline using cards and they all play out simultaneously.
Outside of combat you can use your abilities casually or with maximum effort. Putting your full effort into them gives you a significant bonus, but it costs Stamina. Stamina is also used to make your strongest attacks in combat, and you have a limited amount between rests, so you have to carefully decide what's worth it.
Those are the basics anyway, it's a fair ways off from being playable yet.
