There is an Android release of the new version to try out:
Download MazebertTD-1.5.4.apk (~30 Mb)
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.
