I've noticed that the spacebar does not seem to work the first time you tap on it, but should work fine toggling the dialog box visibility afterwards, so it is admittedly a bit wonky in that regard. Also, the parallel command for this spacebar thing is launched at the beginning of a given scene, so loading an older save bringing you in the middle of an ongoing scene might explain why it doesn't work. Given the tools I am working with (not Ren'py, although I should totally get to it eventually), this is the best I can currently do. My apologies.
As for the minigames, my original intent is still to make the player struggle, since those are not supposed to be easy victories. Those women are strong, after all! So I adjusted some settings to make them easier in comparison to what they were before, but I still deliberately want them to be a little difficult. I don't think I will lower the difficulty beyond a certain threshold.
Still, thank you very much for your interest in my wonky and quirky little game, and for taking the time for leaving a comment. I hope my future works will meet your expectations better.
