Does this DMC3 version allow for style changes on the fly like 4/5, or is this classic version with styles being changed only at checkpoints?

Classic of course...

Thanks. I would prefer to have Switch version change on the fly (or option to choose between them), but it's still ok.

For what it's worth, there are mods that add style switching as an option. I think they work with this version? But I haven't tried them myself.

Thank you, I got myself the mod. Will see if it will work with GOG version :)

I love the game and have beaten US version on PS2 long time ago, but for replay I would like to have more fun with switching styles all the time :D
