I was dissatisfied with other race-style mods that overcomplicate their mods and end up with large compatibility issues, so I've made a simpler mod that just adds a configurable time to your run on death, and revives you, so you can do races against your friends on even the most wild of modpacks!
Note that this mod does not set your run seed, if you'd like that feature, debug toolkit allows you to use the "seed" command to override the seed. (override_run_seed doesn't work)
The configuration allows you to change how much time is added to the timer on death, and even allows you to further compound this time for each death. (It also allows you to toggle the artifact/itemdisplay!)
