Love the art and all the characters. Gameplay is quite fun overall, and seeing clothes blown off is definitely a major kink that I don't see enough of. Couple of small points I don't see mentioned below, though:
Small thing, but would really like a way to speed up the rewards section. If you get 30 tickets (which I did one game), then you have to wait to process each one. If you roll the 500 reward, you are left waiting there for probably about a minute as your money counts up one at a time, with now way to skip... and then it waits for you to click again to roll the next ticket. Something to do all remaining tickets, or at least a way to skip the coins counting up, would be highly appreciated.
Other thing - Even though the attack patterns are different for each character, they are all quite similar. It would be really cool if there were character specific mechanics. The game is quite good as it is, though a tad repetitive - but I could see some added depth of, say, for some characters, your base stations other than missile launch stations actually do something (whether power a passive ability, or your opponent gets more powerful when they destroy some, etc). Another could be areas that appear that you don't want to have missiles explode on, possibly spawning UFOs or similar when you do so. Finally, having character specific missile types that are more distinctive would be really nice - say, ones that follow curved paths, or not all missiles are the same speed, or even a missile that requires more than one hit to destroy.
Still, like where you have gone with this game so far! It is your game, so feel free to take it the direction you want. All the characters are fun and charming, and the art is definitely a treat.
