Hi again! A return to main menu option would be good, however I'm probably going to wait till I have a working save system before adding it.
I'll look into that bug, I suspect it has something to do with framerates. And yeah, I hadn't thought about the pause menu during dialogue,
The fireball animation will come eventually, I'm still undecided on the full mechanics of how it should work so I'm also going to wait till that's nailed down before spending time on the animation. Either I'm going to keep it so that you get unlimited fireballs, or that you recharge them by interacting with braziers to help make puzzles.
