I feel bad for the negative reviewers who were disappointed when the Kishi didn’t work for their favorite game. You can easily avoid that if you first check to see if the game supports controllers. It’s up to the game developers to add that feature to their games, and they will usually say so somewhere in the game description. You can also test it out by connecting a PS4 or Xbox controller to your phone via Bluetooth. If the game works with those controllers, then it will almost certainly work with the Kishi. The bonus is that the Kishi gives you a wired connection and Switch-like form factor (no need to carry one of those controller phone mounts). I use this on my train rides everyday with Anki, a flash card studying app, and occasional gaming breaks. I looks, feels, and performs like a high quality device. 5 stars easy. I really hope that v. 2.0 adds data to the charging port so I can connect my hdmi adapter.
