So im not in fl0w but i like striking mods so sorry for the invade
i have an interesting mod called pfy_shuwip05.tbm that showcases a few interesting things you can do, like increase the force you retain when u come into contact with any surfaces, an overhead lattice, an updated point system, shorter tf for the first2 or 3 turns to help you counter openers, and making some bodyparts dq-resistant
other things i havent made mods for, like making walls/floors do damage if you hit them, only dqing when you hit a wall/floor super hard & only for certain bodyoarts, like maybe just the torso, making only some bodyparts completley anti-grav - like maybe you make the limbs anti-grav and make the rest of the body heavier or something
these are all new things though, and maybe you won't want to try things you're not familiar with
