It would be nice to know about hiding ealier . I ended up jumping off a box in mid air to pass a level before learning about the hide.
L13. The little outcropping on the left looks like it can be jumped on when it can't
L14 The movement is a little senstive with the starting box.
Would be a 5. But did not explain the mechanism.
It took me until level 13 to figure it out. You cannot go up as a dash. However if you hit a wall while dashing you climb the wall.
My tip for beating the game. Find a video with a black frame. Load the video into two copies of VLC and enable always on top mode. Use cinematic mode for the game and arrange the VLC windows to block out the sides leaving only the center and a strip down the bottom.
