What I Think You Can Improve...
Well this game was excellent and i know that it took you very long time to finish...
You can do a second part or update this one and i know that will be all history number one if you do this:
1. First you can do more than one level not just the one that after 25 waves it becomes monotonous.
2. More gameplay modes like after certain quantity of wavesyou can do something to repair your ship and you can fly it
3. A save feature beacause i know that everyone that had already played this hates when they die and has a lot of progress
4. dificulty levels so the newbies can get used to the game and the people who likes the challenges can get more...
5. more guns more ammo type and something like someone that can help you to kill the bugs
6. more variety of bugs and more easy ways to kill em'
Well Well Well I knw that you cant put this all in one game but you can either to try it Or... YOU CAN DO A GAME SERIE! nice idea huh? well the game was excellent and I hope this helps AND YOU BETTER HAVE FRONT PAGE WITH THE SEQUEL OR ELSE... well se ya later
