Had C64 back in 80s. I've just recently stumbled upon this:
I had no idea that, apparently, porting to C64 is a thing...
Oh, wow, nice find. Apparently for some indies it is a thing, jokingly or serious, to support devices they grew up with. I was aware of Sam's Journey from 2015, which only came out on C64. Also Pier Solar and the great architects was released 2010 on Sega Genesis, before it was ported 2014 to more modern platforms, and 2015 to Dreamcast. Apparently Dreamcast is also a very loved platform targeted by some newer games.
