So watching through this, even if we put aside the fact that they've stolen artwork, this was planned to be the first big gameplay showcase of a game that they presumably thought was ready and, like we all expected, there really isn't much to it. Spacewar! was more complicated than this. Despite this, they've saddled the game with three separate control systems that the player seemingly has to choose each time, two of which require use of the touchscreen to replicate twin-stick shooting, because the Amico controller just doesn't have the controls they need to do this most basic of games properly.
Even worse, despite the total lack of complexity it's not running smoothly. It's something like 40FPS maybe. If Amico is struggling with this then it'll struggle with virtually everything.
