on f12 (take a screenshot) the game closes. if you play on a joystick, it shows the keyboard buttons in training mode

I happen to love 3rd person rail shooters and this is a heap of fun with multiple ships to unlock, 3 ships to start with with very different weapons, upgrades, good music, and multiple resolution support including a lot of aspect ratios a lot of games don't support at all, and yes 4K native support. This is a cheap and very cheerful non stop action game even with a little story behind it with a 3D rendered cutscend - check it out! What a pleasant surprise it was for me!...
