I hate to be the historical stickler (who am I kidding I love it) but thumbs up at the arena meant the crowd got what it wanted and they always wanted death.
FIRST 3 LEVELS NO MISSING: First of all you only need to reach, not finish, day 3 without missing. I managed it like this. I built turrets with my starting cash, dodged the best I could (I got hit a few times, I had lost about 1/4 of my health at the start of day 3) and didn't fire my gun at all. Much less frustrating than trying to maintain 100% accuracy.
Both you and your co-producer need to take a step back and look at what you have done. Not only is this game just plain awful, you didn't make any of the art work yourself.
if you are not going to give the players the ability to set the towers targeting priority, then at least have them do it with some sort of intelligence. Towers should never be shooting at an enemy that just came on screen when then are enemies doing damage to the tree. 2/5
tutorial fail...'Click your Hero's Avatar, then select "View"'...I think you mean "Check" 1/5 just cause I'm feeling mean and haven't had my coffee this morning
giving this a 1/5 as a tutorial it is pretty weak without a back button, even weaker because it doesn't give easy access to the scripting used to achieve each of the behaviors.
If you are going top use a real asteroid as the antagonist in this game at least get a few facts straight. 1. 99942 Apophis is coming in 2036, not 2012 2. 99942 Apophis is ~300 meters in length, this makes it about the size of the Rose Bowl, a far cry from "the size of Texas" 3. it is highly unlikely that it will hit us. It's all right there in the wiki http://en.wikipedia.org/wiki/99942_Apophis
