thanks for playing and for the video!
sometimes the cards were highlighted but it didn't mean anything in particular
you're right, i should be more consistent with what i use "lighting up" the skills to indicate
I don't know what to think about the limit mechanic. Is its function to avoid one shotting the opponent? Big chains are exciting, why punish them?
yeah, and likewise with them chaining you. red 
skills are designed to lower limit and let you make big chains, the idea is that you'll add limit-lowering skills and synergies to your build to get around problems with Overlimit as the game goes on
