Played the browser version you uploaded.
I like how to camera follows the player. Look nice.
I find the game a bit to hard. I took me several tries to beat level 1 due to the limitation of available items.
It did not feel like the green dots were helping me at all.
Therefore I had to build a catapult with 2 attracting magnets at the side. This way the ball goes through the middle.
I would have liked to have no collision with the magnets. I feel this would have made it easier.
Good job on finishing the game.
