Not too shabby, not too shabby at all. I like the title theme myself, it's got a pep to it. This is a somewhat softer version of it, but I like it also.
What you really need, not what you think you ought to want.
Heh. Before I saw the video I actually thought it would be your custom MIDI which would replace the original title music.
I was also looking at the custom level which you showed in the video. Apparently you firuged out how to use the editor pretty well, that's nifty. Actually, for some time already, I'm thinking about making another update to the editor. For example I have some ideas how to improve the Pattern mode.
