There is an Android release of the new version to try out:

Known gotchas related to multiplayer:
- Playing over cellular network will probably not work (due to symmetric NATs preventing P2P)
- Don’t expect super nice user experience if there are interruptions like incoming calls etc. However, interrupted games can always be resumed together
- Can’t promise that all simulation bugs are fixed by now
Besides that, I’d be super happy if you’d give it a try.
I think the biggest problem right now is the matchmaking, since there are not many people looking for/hosting multiplayer games at the same time.
Maybe the forum would be a good point to look for fellow players, who feel adventurous and want to try a coop match with others.
