Instead of upgrading your ship and then wasting money on new weapons, buy new ship, switch to noob ship, buy new weapon, then switch back to new ship and your new expensive weapon will be copied to all the slots and you'll only need to upgrade one of them.
The "Play each stage at least 3 times achievement isn't firing for me. I played them all normally, then did all of the special challenges, then got all gold leafs, and even quickly went in and out of each level. I still don't have the final achievement for the hard badge.
I just got to level 7. It wouldn't let me check the opponents army. In the battle both of our names are written backwards. I have -15 health and he has 9999 (written backwards of course). The hints are back and can't be closed and I can't start the match. I've beaten the game 4 times now and I still don't have the badge. This game is an alpha release. Your QA is crap.
