Thanks for playing! I agree that an online leaderboard would be great. Perhaps one of the first things I'll want to build if I'm going further with this! dreamlo looks great for ad-hoc use in game jams, although I'm not sure if an unverified leaderboard would be suitable for more serious projects. The code I'm using already has replay support (that I was going to make an in-game tutorial with), so I might just go ahead and invest in a custom solution with replay sharing and verification instead (that is, if I'm going to)!
