I downloaded it a few hours ago and tried it out a little. Pretty cool. Was wondering what game engine you used? I want to make something simple and anime like for android game market also. Stumbled across this and figured I'd ask for some direction

But if you don't know any programming language/development tool as yet and only going to start learning, I would rather suggest Unity. I think the majority of recent successful indie games both for PC and mobile devices are created with it. If you are serious about game development, good knowledge of Unity will be a lot more useful in the future, so no matter how much time you'll spend learning it, that time won't be wasted.

Is this your first game or do you have some others i could check out?

All my games can be found at Google Play if you click on "more from this developer". The same girls also appear in "Shoujo City" anime game:

A new cool feature is introduced in version 1.3 - coffee room. Now you can relax with a cup of coffee before (or after) next sniper mission. Drinking coffee will improve your aiming and concentration for one mission.
