I choose the first level in the first world and the game immediately crashes. ### 4/5 — Very good game! *2016-07-15, version 1.3.1* Great game! Plays like King of Thieves. The jumping is a bit delayed sometimes and you have to press twice to get Yarn to jump.

But only about 60-90 minutes of gameplay until the 40 levels are completed. ### 1/5 — Disappointing from the (non) start *2016-07-06* Downloaded and deleted twice and cannot get game to load on my iPad 2nd gen; get to level screen and app simply closes. Too bad as I was looking forward to trying it. ## Frequently asked questions about Yarn! A Jumping Physics Game ### What is Yarn! A Jumping Physics Game about?
