Ringold

Its trials come with handicaps of their own, listed below.

Claim all three Timeline items, Present, Past and Future, to open Tier 3 World Ascension. Each win raises the level of your next attempt, and a Hard mode keeps a level of its own. You move with W A S D or the arrow keys and shoot with Space. The bonus code ResetRingold resets his level, and SkipRingold brings his level 1 HP down to 1.

Starting it switches off the Nitro Booster and moves you by hand; you can set your top Move Speed by clicking it in the Ability menu. Your best is sent to Steam’s leaderboard, as long as the run is a fair one on your main save.
