The first time I played this it was fun, but not super interesting. However, since then, you added the yellow paper and I think that was a really smart idea because it makes it much harder and you actually have to think about what you are doing. Its a fun game and a silly concept.
Also, this may be just me because I see a lot of people praising the audio, but I didn't really like the shooting sound. It was super loud and really annoying after a while. Maybe try a softer sound and some light music? Again tho you got a lot of praise from other people so maybe don't just listen to me lol
Anyways great game!
