Thanks for the detailed feedback!
Yeah, those bugs are the ones we knew about but didn't have time to fix them.
The indication/hints definitely can be organized better, yeah. The radio dialogue button relies on sound but sounds tend to bug out in dev build, and drone return is silent, something more on 2D UI/guide might've helped. Also some metadata on level artifact count.
Btw, once you scan level's target object (rest are optional) a notification about being able to return the drone will appear, and then the flashing drone return button can be pressed, ending the level.
