I was just getting irritated that I couldn't read signs when.
Halfway through playing, I realized that this game doesn't function like normal JRPG battles. Optimizing attacks? Nah. It's about gambling to survive. Even though it's short, I was often conscious that I was trying to stretch out my life, and that the stakes were escalating.
I think layering mechanics on the coin flip could be interesting. It had me thinking of games like Bravely Default, where the calculus of battles isn't driven by typing or understanding the interaction of stats, effects, etc. It's about making critical decisions to stay alive.
