Cuphead - Djimmi The Great - S-Rank with Twin Heart (Current Patch)
Sorry guys, not a speedrun video!
I'm uploading this to prove that Twin Heart does not reduce your damage to the point where this level is impossible to S-Rank due to the time requirement. As you can see, I made it comfortably under the 02:00 mark (which is actually closer to 02:09 for S-Ranks due to how the formula works).
