great mod, im probably gonna keep this on when playing sm64 with my friends
it feels very good to play with (except for the lack of momentum pls consider adding it) and its overall really fun
only complaints are the fact that you lose speed really fast (especially after uncurling after spindash). and theres kind of an incompatibility with Extra Characters that causes issues with doors but other than that this is great.
for conserving speed the best option is to stay airborne or stay rolling as much as you can -- and try not to let go of the analog stick when landing as that brings you to a complete stop. also i will say this mod is relatively outdated as of now but its getting a big update very soon. try to use it alone or with non-player affecting mods for the time being, expect the occasional bug
