With this latest build it should actually be possible to get all of those missing / malfunctioning achievements. =)

All you should have to do is visit the upgrades page in the game and you will get all the achievements for items that have been fully upgraded. (Due to an odd glitch, you may have to go into the upgrade screen twice to get them all if you have already unlocked everything…)

While I was working on the game tonight I had a couple ideas for making it a bit more challenging at later levels. For now, though, I’m going to bed.
