Interesting concept. I found I had to do a couple tries and revisit the help screen a lot because there was no cheat sheet anywhere I saw for the codes. Also, when inputting the codes, there was no form of feedback I noticed so I couldn't actually tell if what I was doing was working until I finally got a bomb off. Novel idea and nice drawn art style
Very difficult management, it could be easier to do. The graphics are cool, the sounds are very loud, there is not enough volume control, and so the idea is cool.
Great, funny entry! The gameplay creates the feeling of having to remotely defend against the aliens well, and the feel is very consistent. You did a great job of putting in some subtle touches, along with extremely UNsubtle touches, to produce some very funny moments: The character's walk cycle, the slider noises, the just-frustrating-enough keypad system, the screen rattling explosions... I laughed out loud a few times, and I really enjoyed the time I spent with the game. (Even though I couldn't end up beating it...) I will echo a previous commenter that it would have been nice to have a way to see the codes while playing. Also, it took me a few plays to notice I could walk around, even though it was in the instructions. Overall though, an excellent entry! (Also- I couldn't rate you in mood, but the atmosphere is very cohesive and you did a great job.)
Edit: Fixed!
