Excellent job Hazzerz. I just tried your theme for the first time (via SVN) this afternoon and it's freakin' awesome.
I know you're not done tweaking it, but the little things don't bother me in the least. I can even run it on my old laptop (turning off stage animation) and the overall theme directory size is fine, maintains good fps, and the animated star notes look great. I am running beta 2, so like with most current themes there are some font size issues, but nothing that's a deal breaker. Overall very impressive for a completely custom theme.
Personally I need more time with it to recognized the hopo notes instinctively. Have you considered another style for them by chance? No biggie, I just gotta learn to adapt my reactions as I keep expecting "pimple heads" whenever I see round notes. I'm not judging, for all I know I might end up preferring the smaller notes for hopos. My plan is to run a few hours of expert charts this evening and get a real feel for it with an analog controller.
BTW, I busted out when I read "stay tuned for my next theme, rectanglez".....classic!
Thank you very much for sharing your work and I look forward to your updates whenever available.
