I don't know how it was in the SaGa 2 port but yeah, it's a wee bit janky.
Hopefully they'll fix this. Not a dealbreaker since it's just a sprite based game but it does feel weird.
In my humble opinion, a remastered port of a 1995 SNES game should not be running in 30fps while its original counterpart most likely will run at 60fps in an emulator.
At least they didn't put unremovable bilinear filtering on top of everything, so we'll just have count our blessings, I suppose.
