I should have the achievs for reaching floor 3 and level 5. Tried it on Normal difficulty. Nothing so far. Yes, I was logged in on Galaxy the whole time. What gives?

The achievements don't work for me either, so I don't think it's just you. Over a month without any response is disheartening, too. Hmm.

Strangely, the second time I started up the game, the achievements began working. I noticed also that the daily challenge option was listed the second time, but not the first time I started up the game, so I'm wondering if there's some connection there...

In any case, I'd suggest that anyone with similar issues try restarting the game first.
