Neon White

Red’s Hell rush is arguably the easiest of the 5, as it’s only 8 levels long (same as Purple and Yellow), but you also have the option to use the Alt Fire/Discard, and most of the time you can pause and orientate yourself (bar the final stage).

All Hell rushes are unlocked by completing the game on the good ending (collecting all gifts unlocks this option after the final boss).

Below is a clip of one of my runs. It’s not intended to be a “speedy” run, just a safe, clear run intended to aid those who may need it. There are many opportunities to skip levels which I didn’t take. By all means, use my video as a template for you own runs.
