I've been making a little arcade game as something to practice my Java skills (I started 2 weeks ago).
It could be improved greatly. If you have any tips on how to do so, feel free to suggest stuff.

Fun little game to play, nice job!

One thing I would like to see would be a menu to start a game rather than it starting straight away, and when you lose it returns to the menu rather than closing the application.

Your browser will say it can be harmful because it is a .jar file. These are similar to .exe files except that it has all the project files compacted within. The virustotal link shows that there is no problem with the file.

If you really don't trust it then feel free to read through the source code. Other than that there's no other solution I can think of tbh.
