although I didn't finish it (stopped at the third level trying to get across the moving parts) I had fun playing it! The main mechanic is simple but it has depth, because each missed shot has a consequence. I think its quite fun to play, and I also think the ability to do smaller shots + shots while you are landing would make it (i.e. to prevent from rolling into sewer water) would make the gameplay even more fun.
I also really appreciate the story and the humor. I loved the messages when you die or complete a level :)
