The sun will not explode. This only happens to extremely large stars, and it is called a supernova. What our sun will do is expand, but not on the scale proposed in this game. Therefore, this game is a scientific impossibility, unlike Bloons. (that stuff makes sense)
you guys need to work on your player models a bit. the gameplay is fantastic, and very innovative. the one problem I see is graphics. I understand that it is not easy to create a flash/unity game that has fantastic graphics, but please make the characters less blocky. overall, on a scale out of 10, I would give this game a 9. keep up the good work. (also, lower the prices. takes a bit too long to buy anything permanently.)
