This is it: https://jtruher.itch.io/shmup-sprite-pack It looks like your generator's work. I like your generator. Sorry it took me so long to get back to you. I lost it in the sea of itch.io stuff.
It is similar but these sprites are not my generator work :)
ok cool. I coincidentally found another shmup sprite generator last night, but I like yours better as its stand alone :-) I just like seeing what it comes up with.
