Yeah, I get that. My submission is a choice-based game ala "Reigns," and after running the game dozens of times I knew exactly when the game would unlock input for the next choice, and I hit A to make my decision almost exactly when that window opened. It ran pretty great and I sent it to the team for playtesting at like, 1am.
It never occurred to me that a new player would spam the A button trying to see when the input window opens, and when my teammate ran the game it was just glitch after glitch because of tiny windows of time when the game wasn't properly ignoring the A button. I guess this jam taught me how important lengthy playtesting is to understand how an actual player interacts with the game.
