I thought at first that I was looking for Artist Idle, but that game doesn’t contain any mention of computer parts. (I specifically remember there being a water clock upgrade, to start automatic pixel production, among others.)
I think it was called something like “CRT Idle” or “Scanline Idle”, but neither of those searches have given my any results.
I’ve checked on itch.io and galaxy.click, with no success. (As well as googling it, duh)
That was it! Thank you! :D
