How to Upgrade the Boat Engine and Unlock I Am Speed

What to do

1. Finish Lighthouse and obtain the boat keys before budgeting for travel upgrades.
2. At each newly unlocked island, inspect the shop inventory and compare the displayed engine improvement with the gear needed for the next boss.
3. Buy the first affordable engine upgrade when travel time is limiting progress; Steam tracks a separate Getting an upgrade achievement for improving the engine.
4. Continue the story and recheck later shops rather than assuming the first engine is the maximum tier.
5. Buy the item explicitly presented as the best engine, then verify I Am Speed in Steam before spending remaining money.

Before you leave this page

Prices and shop placement may change, so this page does not hard-code a number that could misdirect a new save. The achievement condition is the reliable boundary: the best-engine purchase, not total money spent or boat distance traveled.
