I've posted a video walkthrough of the Hansel & Gretel adventure on YouTube, with commentary.

The video is timestamped so you can jump to where you want.

The text underneath the video contains the complete solution (generals & troops) so following along with the video is easy.

Remember you can play YouTube videos at up to double speed (or slow it down to better follow what's happening).

Quality is 1080p at 60fps.
