castle siege

@Don G Rowe Took me quite some time to find it in the dark, but here it is:

Spoiler

There's a hidden ball to be released by a darkened draggable, right inside the side entrance guarded by one single zapper bot. Free Camera might be needed.

As for @Ikku , welcome to the forum! Like Don, I also almost thought the level is unsolvable until I stumbled upon what's missing. Your first level looks nice with the castle, with a lot for B to explore. As you can see how Don and I had trouble with finding the hidden element, a suggestion for your future creations would be to avoid hidden / darkened parts as most players consider them as a matter of chance / guessing than logic, as requiring more searching than thinking. We look forward to your future levels.

Your level is nice to me with of course a hidden element which is not so hidden when analyzing how things could be achieved. Moreover this is your first level! So, thank you for sharing
