### 2/5 — No good antmore

*2013-11-06*

This was a neat game until ios7.3 came out. Now I can't enter my score anymore. And just when I'm advancing the aliens get faster. I'm not spending 10 cents on an app. When I get tired of this one......which is gonna be soon.... I'll find something else.

## Version history (last 5 releases)

### 1.65 — 2012-07-22

- Bug fixes, performance improvements.
- Added link to the new Space Cadet Defender HD.

### 1.60 — 2011-08-09

By popular request we have added the ability to buy upgrades to your ship with in-app purchase. Have you ever been stuck on a level and had the feeling that if you just had one more upgrade then you'd be able to pass it? Well here's your answer, go to the Upgrade screen and simpley buy the upgrade you need and then continue on to destroy the enemy aliens.
Note that none of the game balancing has been changed as a result of this update. The aliens are just as tough as they were before and they drop the same ammount of money as before, this just gives those players that need a little extra help to be able to continue on.
