Well Done
Gameplay-Was smooth and everything worked well. The only flaw that I found throughout the entire game was the large numbers later on. The problem wasn't that they were hard or too many, but the collision was off. The larger number may not even be touching my small 10 or even a 2 but that 2 would slip right by and hit me no matter how much I shot at it.
Sound-Music was good, but with no variety. This didn't really detract from the game too much since most of the time I was focused on finding the right way to kill the two 115s coming at me.
Graphics-Good enough for this game I thought. The turret was really cool with the pulley system on the side. If you added too much to the numbers they could get hard to see and impede the gameplay.
Overall-This game was really amazing. There really isn't any need or use for powerups since it only relies on your reflexes and thinking skills. Although it is very basic in that sensem, the concept of the entire game is very original and has a high replayability.
The only reason this game doesn't get a 10 is because of the problem I mentioned above and there was one time that a 1 came flying at me. Now since this game isn't called 123 as you said then I shouldn't see anything below a 2 flying at me. I don't know if this is a glitch or intentional, but it should be fixed.
Great game and keep up the good work!
