like the above comment stated, asesprite it's probably your best bet. if you've got 20 bucks to spare, it's definitely worth it. though i haven't used photoshop before, (i'm unsure if it has anything like a spriting tool) i'd stray away from using regular art programs for spriting, since they usually aren't made with it in mind. i used paint tool sai for spriting for like, a year, and it was ridiculously tedious and not worth it at all. do yourself a favor and just go for asesprite lol
and yeah, asesprite does have a learning curve if you aren't familiar with art programs in general, but practice will pay off
