Simple and yet awesome, one of this games that keeps you playing untill all achievements are completed. If you are planning on doing a sequel i would suggest adding more types of trees, somewhat similar to other TD, more story behind campaign (this one is really great and i smiled when i read what I've faced here, and what means are at my disposal, you could make it lenghtier and add some more text behind every mission. Not much, just you know, some). Keep it simple as it is, and continue to listen to fans, 5/5 for that. Great game, great developer ;)
