This is so cool! This is a very solid way to make combat in rpg more fun as finding the solution is mentally straining but feels like you have worked that powerful strike.
If I may say I would love more breathing time, I would have loved a more calm exploration to compensate the frantic battles. I think with some tweeks and layer added to the combat(I imagine to throwa fireball you have to solve a harder calculus...but the combat is already that good) and a world to discover and take at your time it would be very great.
At least an rpg that I would play because I get very bored by the classic systems.
Great work looking foward for more!
