Oh, just saw you were streaming the game! :D I now see your struggles.. ^^' To jump higher you have to hold the button longer and if you use the attack at the highest point of the jump you can get over the steps easily. You can also use the attack to stay longer in air while you move, so you can get across the holes and reach the bubbles far above. I grew up with all those platformer tricks, so it just feels natural for me to do them. I guess a tutorial scene might help in such situations. Anyway.. Thanks for playing! :3
