A few months ago, Nintendo and Marvelous collaborated for the fairly unusual act of releasing a demo of their upcoming mech game Daemon x Machina, months and months ahead of release. The demo was explicitly intended to get feedback for the final game, which Nintendo and Marvelous say they gathered. Now they have released a video saying exactly what that feedback yielded.

If releasing a prototype demo was an unusual move for Nintendo, then releasing a trailer showing what changed is just as strange, but you can watch it below.

There’s numerous changes, like motion controls getting more sensitivity options, indications of where an enemy is shooting at you from, the speed and momentum of player movement, and many other things. As someone that was unimpressed by the initial demo, I am pretty surprised at how different the game looks to play now. It also just plain looks better graphically than it did a few months ago.

Daemon x Machina releases on Nintendo Switch on September 13.
