Hi, I'm really interested in UFO. Does anybody know if it supports Cross platform? Between PC and Switch for example?

love this type of game. any similar games out there?

Some have a circle with a grey middle and green outline, others have a yellow middle and green outline, idk what either means

I was wondering how many people I can play against for the online multiplayer.

So I've been at this for at least an hour now, and World 5 Objective 5 - "Break 10 crystals" - just won't unlock for me. I've broken well over ten crystals, both with a ranged weapon, the drill, and the bomb jump, but still nothing. This is the last objective I need in the first five worlds. Is there some trick to this objective that I'm missing? Is it bugged?...
