It took me 45 deaths to make it to level 5...but as really satisfying once I got it! I think the main point I was stuck on was I couldn't understand how to use the extra jumps I got. For level 4, I thought I was supposed to get the 2nd closest cherry to the ground, and I was confused why the 2nd jump wasn't working after I got the first cherry.
And I randomly discovered that that it only works if I change directly and then I passed that level almost immediately.
I think level 3 could do a better job introducing this mechanic. I still don't 100% get if my explanation above is correct.
