Toki Tori is a puzzle game made by Two Tribes for the GBC in which you must use the skills available to you to advance through 60 levels, separated into 4 worlds of 15 levels. Skills include building ladders to cross gaps that your jump can't make, warping to other areas of the level and building gaps for enemies to fall through.
ThunderAxe31 completes all the main levels in record time.
We also have a run that does all levels, including the harder ones, which you can find here.
