Looking at the world map, I'm pretty sure I'm stuck in room 3 (same room as your second screenshot). I can't get the seed to point the right way to get me up there. If you have tips, I'll try again -- but I spent almost 10 minutes trying to roll a seed to where it would let me jump up and couldn't figure it out. I'd love to play the rest of this game!
The Tip is ... you just throw the seed on that point. The most important thing is jumping. You have to jump from almost the top. It must be a position so that the head doesn't hit the top block. If removing a block at the top might be easier.
You can actually hit the ball slightly to change direction. But it's too random.
Hope you enjoy playing the game.
