Wow!! This just blew me away!! Incredibly designed!! The whole "Idea" *hahaha* behind this is an awesome take on the theme for this Ludum Dare! AND THAT SOUNDTRACK!!! I've been playing guitar for about a year and a half now and that was just beautiful playing!! All around wonderful game, however (I'm not sure if it was just me being a scrub but) the very last obstacle seem uncharacteristically more challenging then the rest of the game. It took me a good amount of tries to get past it! But then again that might be how you wanted it and I could just be a bad gamer hahaha!
All in all this was amazing and I can't wait to see what else you come up with!!
