I quite enjoyed this game, although there were some things that could be improved. I agree that using the deodorant in the tutorial image as opposed to for instance the pen is a little odd, but I had no issues figuring out how to play. It would be nice if we knew what the range was on the towers though.
The game seems to reset when completing a level as well as opposed to returning to the room overview, which feels a little weird (It's the small things that count!). I liked the music and environment but would like a little added clarity.
