SDL 2 Shooter - 2D shooter with online highscore table

I was stuck for something to do today, so I took one of my game tutorials and slapped an online highscore table into it. The game is a free download from itch.io:

The aim is simple: shoot the enemies, collect the points pods, and get a high score. Arrow keys to move, left control to fire.

Binary is included in the archive. There is currently no way to adjust the sound and music.

There’s a limit of 8 score positions. This is just for larks, so let me know how you get on. And if you have suggestions for improvements.
