1. Thanks for the input, I appreciate you taking the time to play and judge my game
2. A lot of these problems are things I know are wrong with the game but due to my lack of time, inexperience with unity and this being my first game jam(I was pretty bad at managing my time) I couldn't add these things.
3. I like your ideas for weapons and engine system I might add those in after the jam but tbh the code is a nightmare to read so I probably won't. And I agree about the art style, I made it all in paint.net with the shapes tool cause I wanted to work alone (probably not the best idea) and I was pressed for time on this project.
Lastly thank you again for your input, it means a lot to me that you'd write an essay on how I could improve on this.
