I probably sound stupid for not figuring this out but I don't know how I'm supposed to reach the first relay dish. After talking to twent you go up to the long vertical room but there's a platform I can't jump onto so I'm stumped. I tried to see if there was an upgrade that solves this (e.g. double jump) but all I found was the Rovoxx core.

I'm just wondering if this is a puzzle I need to solve (if it is I'd appreciate some help) or if it's for the demo.

Nah, it's somewhere you can't reach. The demo is limited to just moving around and testing the mechanics in the hub zone. The fully game will have all areas, of course.

Thanks SolarLune for the clarification. It makes sense now as I can even see the a platform hanging in the wind. By the way, the game is really fun and the hub is engaging and really made me invested and excited for the next part.
