Hello all! I'm new to speedrunning but I managed to get both a sub 00:19 and a sub 00:18 on 5-4 Leviathan. I was submitting the sub 00:18 run when I decided to double check the rules just in case. I then noticed that the no mods rule specifies that texture mods are prohibited. I have added some custom textures and music to the cybergrind, but to my knowledge those additions have 0 effect on my 5-4 runs. I figured that these runs will probably still be ineligable, but I figured I'd double check and ask if the no mods rule applies to all modifications to the game or just those that would appear on/affect a run. Thanks!
Adding custom music and or custom textures to cybergrind is intentional and available for everyone, so it does not fall under "Modifications or additions to the game's files are prohibited." ruling. Feel free to add whatever music or textures to cybergrind you want.
