This game ran fine for me on an iPad pro. I had none of the glitches other reviewers mentioned. The screen changes weren’t noticeably slow. All in all, I liked this game, even though it was on the easy side. The reason for only two stars is that it’s pretty short, and the promised additional chapters haven’t materialized as of this date. With reviews dating back a couple years, I suspect we’re never going to see more. I don’t object at all to paying for games; in fact I prefer it to ads. What I object to are broken promises of more content.
