That was a neat one! Aside from the controls I feel it =D Reminds me of ye olde Ys games, both in sound and feel (especially music, though it did have a slight Keiichi Okabe feel). If you would ever make it a full game I'd play it (if you fix the input lag). It was a bit tricky to get how to beat it, took me about 30 tries before I started to figure it out (I got the hint too late though). Overall it felt like I was playing Salt and Sanctuary in the late 80's.
Also, at this rate I hope more people find you to make VGM. Thought I'd get tired of a single track but you really made it work with keeping it varying, even though there were a lack of Evil Bagpipes.
