I've been updating my game Blackshift (https://store.steampowered.com/app/741110/Blackshift/).
It released in 2020 but I've never stopped adding things and tweaking it. Recently I added mirrors that spin when you shoot them, called "flip-flops" because they work a bit like flip-flops from computing.
I'm also tinkering with some new game ideas, because I'd like to make something popular that can sustain me financially, and the gaming market, as difficult as it is, does still seem to value human soul and creativity.
