Thanks a lot for taking the time to test MathHack and sharing the recording!
Watching your play session was helpful. It made me realize that my current onboarding and UI feedback are way too harsh for first-time players. In MathHack, the order you play your cards heavily dictates the battle as you can see through the calculation formula and the initiative to attack. So actually every click matters.
I've recently added an Explore Mode featuring a roguelike map if you ever want to check it out again! Moving forward, I'll definitely enhance the tutorial and UI indicators to make these mechanics much clearer.
Thanks again for the honest reality check—this is exactly the feedback I need to make the game better!
