"So much fun!" finally unlocked, after many times of clearing cache, trying a different browser, redoing it again, etc...

The in-game time was 1 hour, 32 minutes, and some seconds at the point when it finally decided to award me the medal which is supposed to award after only 1 hour.

Maybe since that time I didn't clear cache when it didn't reward, and had just reloaded again, the game finally noticed? Although I did play for a few minutes before it randomly awarded. Just putting it out there this might be a problem medal for people but if you reload the game (don't reset cache!) and keep playing it might award at some point.

And yes it did "award" with a 0 points medal at the 1 hour mark. But not the actual medal. So if the medal popup in-game says 0 and not 50, this is happening to you. Reload the game and keep playing on (but don't reset cache) and maybe it finally awards.

funny and fun

Good game. No idea how you would get the time management medal.

My only problem is that it can be hard to jump with a keyboard.

Great games !
