Great concept and implementation! I like the idea and instructions and logical nature, the different challenges are interesting and I appreciate the ability to try different levels. I feel maybe it needs a reward to give a reason to solve the levels, or something to hook me in. Maybe unlocking functions which give the operator more options like multiple shots patterns, maybe credits to unlock what you want or improve the drone, maybe promotions to allow you to operate in tougher/different areas. Sounds would help the theme for sure, and I like your idea of a hint system. Overall, well done!

great game! its so refreshing to play something that requires a brain once in a while :P. i used to play these kind of games during computer class in middle school :)
