(Shrug) Sure. There's nothing stopping you from loading images of any resolution into Flixel. It uses basic square sprites for its collision detection and level editing. But you aren't actually required to use those constraints for actual rendering. And you always have the option of loading in individual images as sprites…
Thanks Richard, my question was more performance-oriented than workflow, but useful info nonetheless :thumbup: Muzz those games look neat, but I think I really need to get my hands dirty with coding - for more flexibility and stuff.
Can flixel be used for stuff other than pixel art? E.g. some handpainted 720p backgrounds, hires sprites etc. I want to spend an hour or two a day learning some coding and looking for right platform now. Maybe after a year I will be able to actually do some fun indie game experiments :)
