Not a glitch but (probably) a good speedrun strat. So, In "Sky: Children of the light", specificly in the second world, there is a cloud blocking the way up to the exit temple. Normally, you have to summon flying stingrays, wait for them to arrive and climb onto them by timing your jump and then just wait until they drop you off. But my strat is to climb onto a mini-shrine then spam my flight/boost ability (the clouds regen abilities), keep spamming and boom! I reached the exit.
