Cool idea! I was a bit confused by not being able to use WASD properly, but by reading the comments I found out are using a different keyboard layout :D
Chill music and solid graphics, good job! :)

I think I'm missing something since I can't jump high enough to reach any platform, so I'm stuck right after the elevator. I tried fighting all the enemies, then pressing interact on everything (like the little trapezoids), but neither seems to do anything to help me progress? I'm going to refrain from voting for now since I feel like I'm missing something obvious, but until then, here's a few bugs I noticed.

• - The animations seem to queue up and play after each other instead of when they are supposed to (firing in the air plays the "in-air" animation, then plays the "firing" animation when standing on the ground often interrupting the walking animation)
• - The volume sliders in the menu do nothing
• - The music is not set to loop so plays once then is silent in each area
• - Melee doesn't seem to have a purpose since enemies damage you automatically if you are too close (why not just shoot them to take no damage?) (not a bug but I thought I should add it here)
• - Melee animation and hitbox do not seem to work together (animation comes much later or not at all while the hitbox still activates)

I thought the art was nice though, especially the environment. It looks very clean. I like the idea of the iterative music (music grows as you progress).

A really interesting and creative game, though I really think you should look into making a WebGL build, it's actually very easy to do and will make a lot more people play your game since it's more accessible than downloading the game. 

Here is a short video that explains how to make  a WebGL build in a very clear way, I hope this helps! 

Very well done!

Good job!

Pretty creative and interesting idea but I have 1 question... Why not WASD?

Really creative idea!

you draw all game?
