After beating the Warlock, he will appear on the ground next to your thief, at Zone 102. You can click on him to start a conversation. Choose to summon The Ascender and win a fight with him. You will then be taken to a Crossworld where you have the option to Ascend. Hope I'm not too late and hope this helps you!
Quite hard to see the obstacles when you are going really fast. Maybe a full screen or making the shuttle smaller to have a greater view or smth like that. Nevertheless, great game :)
