Thanks for the feedback! I appreciate it :)
I thought restarting from the gameover screen was fairly quick using jump to confirm (though it only works with space, forgot to add the other keybinds), but I'll surely consider replacing it with a short, skippable reload transition instead as well.
And yeah, I see I definitely should've polished the map further to get rid of dead ends or add a few cues, will keep that in mind next time.
