Flawed logic. Spoiler: Shortcut with the winblock draggable raised one block, B can simply step onto the draggable rather than push the last few balls. Also the curved rail caught a pushed ball and held it.
Not much logic, really. Just pushing all the balls. Nevertheless, the level was somewhat relaxing and the design was good, so 4 stars .
Not much of a logic level as said by others. This level doesn't come close to your other logic levels. Looking forward to more challenging ones. Thanks for sharing.
