Ragtime Loop!
Well, I resisted posting a self-promotion till now, but I guess I'll join the bandwagon, heh. I am seriously considering properly implementing our game, Ragtime Loop, as a full fledged game, but it would be amazing to get some proper constructive criticism on the game from people. We've gotten past the 20 vote threshold, but unfortunately the comments have not really provided much insight into how to really improve the game. If you have the time, it would be awesome to get some more feedback! If you do so, I'll do my best to try and play your game as well.
Ragtime Loop is an admittedly ambitious game that attempts to blend the mechanics of Crypt of the Necrodancer with that of Spelunky (I had Spelunky on the mind during the theme reveal, and moving to a musical loop seemed like a good fit to the theme). Play it here: https://ldjam.com/events/ludum-dare/47/ragtime-loop - HTML 5 build only.
Thanks!
