This is how you can speedrun the tutorial.

Level 1. Go to the right and instantly dash and hope that you land on the bump. Then go to the right and dash 2 times to go faster

Level 2. Go to the right then while holding right press jump and instantly dash again hoping that you will land on the stairs. Then go up the stairs by doing this. right, dash, up, dash, repeat. Keep holding right at that part. after at the top of the stairs, dash to the floor.

Level 3. Go to the wall and spam jump. There is also another way. Do big jumps on the wall. That's basically it...

Level 4. Do the same thing for Level 3 but then jump to the left while on the wall.

Level 5. (Going to update this guide soon)
