Damn. This made my day. Does just enough and the controls are tight (at least on VICE). With the laser beans there's just enough challenge. I can totally have seen myself loading this from a PD disk passed to me without a label or downloaded off a BBS.
I really love your having an official music recommendation and it's slick how you integrated it into the web version. I loaded it up to loop on VLC for the complete experience.
One thing I would recommend is including a README in the zip confirming you should load and jump to the .bin directly at $8000. I know that's the standard, but I still had to guess. Obviously, a self loading d64 would be even better. Also, the README definitely needs to include the keyboard controls. I assume they are strange to work with the embedded web emulator, but for me they were something bizarre like 1,2,END, and CTRL.
I really appreciate your bringing this to NG. This is awesome!
