Leaderboard sounds good!
Maybe some kind of reward of high streak, will be good idea.
Coins/stars/points for every 5,10 levels. And Extra bonuses for high as 25, 50, 75 or 100 levels.
(Or at least change game skin at this levels)
To not get bored fast :)
Great ideas! I implemented colors for clock hands. You can set the hours or the minutes to whatever color you want in (Black, White, Red, Orange, Blue, Green, Yellow, Purple). Also added increased difficulty (just more wrong answers). --just uploaded so may take a while for latest build to be live on itch.io
