"Can we create a game world physics system to work with my Euphoria based movement system?"

Creating a custom physics system in Roblox can be quite complex and may require a lot of work. However, I can provide you with a simple script that can be used as a starting point to customize the character's movement based on your Euphoria-based movement system.

This script will modify the character's movement properties, such as WalkSpeed and JumpPower. You can adjust these values to match your desired movement system. Note that this script should be placed in a LocalScript within the StarterPlayerScripts folder.

```lua
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()

-- Customize the character's movement properties
character.Humanoid.WalkSpeed = 16 -- Default is 16
character.Humanoid.JumpPower = 50 -- Default is 50

-- You can also modify other properties, such as:
-- character.Humanoid.HipHeight
-- character.Humanoid.MaxSlopeAngle
-- character.Humanoid.MaxHealth
-- character.Humanoid.Health

-- If you want to use custom animations, you can set the AnimationId for each action:
local animateScript = character:WaitForChild("Animate")
animateScript.walk.WalkAnim.AnimationId = "rbxassetid://your_walk_animation_id"
animateScript.jump.JumpAnim.AnimationId = "rbxassetid://your_jump_animation_id"
-- And so on for other animations (idle, run, swim, etc.)
```

This script only covers basic character movement and animation customization. If you want to create a more advanced physics system or integrate it with your Euphoria-based movement system, you may need to dive deeper into Roblox scripting and use more advanced techniques such as BodyMovers, constraints, and custom functions to control the character's movement.
