This game is kind of too basic for the most part. Controls are very buggy, it lacks background design, and the bullets move too slowly. At least we don't got a cube as a character.
This game isn't really enjoyable, so I have to give it a score of 3/10.
Sorry for giving you this poor score, so next time, try to do better by practicing more. Game design and controls are very important, so if you can try to think what needs to be done, then you can possibly try to pull it off. You can get better at some point in the future. All you have to do is just don't give up.
