It's funny that there's a similar game called "One Shot" at this jam. I'm not accusing you of plagiarism; it's understandable that people can come up with the same ideas. Now about the game. First, there's no sound. It's not hard to add, but it makes your game much better. Second, there's an unclear upgrade called "Size." I understand that you get bigger, but it's unclear what it does. There's still a lot to complain about, but I want to encourage you to keep going. My first game wasn't great either, so just don't give up and keep making games, gaining more and more experience
