Thank you! This game is actually one of the demos included with Mini Micro, so I intentionally kept the feature set small to keep the code short & simple. But I've gotten enough positive response here that I really should split off an "enhanced" version here with features like you suggest. Maybe I'll take a weekend at some point and tear into it.
Or, if anybody wants to learn a little MiniScript coding and lend a hand with it, I'd be happy for the help!
