Feel free to use this in your mods! No need to ask for my permission.
A mod that attempts to reduce the slippery player movement in Doom. This mod is fully written in ZScript and works universally with any other mod.
NOTE: The player speed calculation might be completely off. I only tested with the default Doom player. Will update the mod once I get some better ideas.
