The REDNEG All Stars Swing-by Edition demo on Steam runs at arcade-spec 60fps framerate on a Steam Deck -- no Proton loader is necessary nor is it required to run the demo either.
Like dreamer (the original release) is actually a lot of fun but I still need to up the difficulty
I went through all stages on maniac and one shot them, did the trial mode maniac and expert and 1CC’d both on the first try, that put nightmare mode up on the select screen but it’s locked. I gotta figure out how to unlock it and then I might turn on suicide bullets
edit: alright, so finally, all world tour + expert mode + counter on felt real nice. it was the first time I felt really challenged and I only made it to stage 6 on my first try. kinda annoyed by having to unlock everything
