In +1 Speed Evolve, every step you take adds +1 to your walkspeed, and that speed banks into Wins. You start life as a Squirrel and spend those Wins to evolve up a fixed animal chain, climbing toward faster, fancier creatures one tier at a time.
Each evolution stacks a speed multiplier on top of the last, so the further you climb the quicker the next batch of Wins rolls in. The trick is to keep spending instead of hoarding, since sitting too long at a low animal just leaves you crawling while everyone else sprints ahead.
