I completely agree with your comments. Because of the unpredictability mechanic it made the pacing pretty challenging. In the end i decided to keep that level instead of scrapping it just to keep a little more content in there. The other levels were passable to me because they can be completed with any missing mechanic. I actually had a timer in there and got rid of it because my kids enjoyed playing around with the different ways and moves to complete a level. Thanks for your feedback!
