7/10 score

The idea is interesting, but art usage could be better. You made it stretch weirdly, but you could use nine-patching for better look. Controls are not very good - you don’t have feeling that you control the player.

I don't think I have anything to add since as others mentioned, the movement felt a bit strange and there's no audio. Although I do think the idea was interesting though.

the movement feels really weird, you should do it with a velocity vector and not change the position 20 pixels per frame (idk if it is actually 20 but it is kinda bad)

i couldnt really understand were the theme was implemented

the art was cool

sadly no audio

Silent , and inaccurate physics ..

But great Graphics , loved them!

Tested on Lubuntu 21.10 x86_64 (GNU/Linux)
WORKAROUNDS
FileNotFoundError exception @ main.py, line 68.  Case sensitive!: missing Assets/hard.png but Assets/Hard.png exists.

There is no music or sound in the game.
The graphics are too simple, I mean, there are no animations or visual effects.
There is no physics.
The character moves very fast and continuous when you fire the gun.
There is no application of the game jam theme.

Difficulty selection is appreciated.

Score: 1/10
