Trouble when connecting a gamepad + supported languages + trial version
* On some operating systems, the touch action malfunctions when an input device like a gamepad is connected.
* If this happens, try disconnecting the device from your computer.
* If a software called Razer Synapse is installed, it seems that the malfunction may occur even if no device is connected

In the trial version, you can play up to 10 days in-game.
The story progresses up to level 5, but after that it stops even if you raise the level.

* If you are considering purchasing, please be sure to check the operation with the trial version.
* English / Spanish can be switched in the full version, but it is not yet implemented in the trial version.
