I really enjoyed the game, it was fun, and the graphics are awesome. I like how you can essentially choose your own difficulty level with the bonus start credits. It would be quite a challenge to beat the game without purchasing them, and making it through mission 14 without losing health. You can buy just enough credits to help you finish the game. Or, if you want total annihilation, you can build up a massive start-up credit amount. You can replay the first few levels with the least number of upgraded towers for a maximum score, which gives you the most credits to buy bonus start funds with (more credits at end of mission = higher score = more credits). I also like the fast-forward button and how it doesn't slow down my old laptop, even with all the action going on, unlike many other flash games I've played with much less action.
