So, I decided to play a bit with a controller, but, while I can map most of the buttons, there is an issue with extending/retracting the claw as it's only mappable to one button, meaning you can't really control it. Would be nice, if there was an option to control it by, for example, holding a button and pushing the analog stick or something along these lines, perhaps. Other than that, it's mostly playable with a controller, even if a bit janky.
