As for those who dont have prblms with changing the game files and logic, Here is the mod for unlimited health, unlimited sprint, faster movement(walk, slow, sprint) mod.
extract this and paste it in
..\Ruins_of_another_world\Ruins of another world Final\異界廃墟_Data\Managed
NOTE: There will be an existing original Assembly-Csharp.dll which u must copy and keep seperately in case the modified version breaks the game. (90% it wont)
else for cheat engine the values for both health and sprint values are 100 float (u can change sprint values in the park and health values in the first H scene)
