Absolutely wild this doesn't use <canvas>! I remember playing this way back in the day, before I was a SWE, and didn't really appreciate that fact. Of course, I'm sure it predates being able to effectively use the canvas... but still! Super cool.
I can't seem to find it online anywhere, but I'm also reminded of the knockoff game "Flea Circus" which I played in grade school :)
This aged really well, I had no idea how impressive this was when I first played it either. The only thing is the cookies, which might break after 26 years:
From what I see, bot the developer of the DHTML version and the band are from Netherlands, and the developer had to take the game down from his site [0]
It's dated 2004, but I'm convinced I remember playing it earlier.
