Interesting game, it looks like it's made in... BLENDER??? Congrats on that!
I will say that the controls are VERY confusing, you should have, for example, W to go up instead of left. In the second level, shooting no longer had sound, and if there's no way to reload your gun, so you're just stuck.
The game is sorta fun, and I love the visuals and audio. BUT, it needs a lot of improvement. Good job.
