I try to do a Variety Megajam every December - the common element is "10 games in 10 days", but the (loose) "10 minutes" requirement was for this year only. Last year it was "playables," and who knows what I'll be into next year :)
Thanks for your interest and participation! I'll be sure to check out your game, and I'm glad you managed to finish & submit something. Looking forward to it.
