Oooh i like how this mechanic sounds, it’s very unique.
However, how will the player know that they’ll be damaged if they get too close but then they will get glucose if they are a bit further? What if the player gets near the rock without noticing it and then interprets that what harms them is staying too long and not too near? Specially if a geiger counter is playing. As someone who’s played Fallout that sound only means “get the heck away form here”.
Overall it looks very promising and i think these questions could be answered once we can use this mechanic in game.
