i dont think "use med kit" and "die" should be an achivement, (although i see the right intention maybe to help the - not so well performing - half of the playership) think about that ;)
Anyways, now there is a nearly perfect "platform" for an advanced, second part :) well done.
Add an Abort option for tower replacement please, i forgot to demolish the tower i wanted to replace and so i had to set the new tower before i could sell the old (or is there any any unseen possibility?) btw. nice work
