Thanks, I emailed you

Great job on the game!

Thanks! I really appreciate it

music were awesome

That's on my friend Red Noise, he made it with a Korg Electribe MX with damn VALVES, perfect for a cyberpunk setting like this.

the player sprite doesn't currently flip to face left when moving in that direction

That's when using the mouse to aim (it always face mouse cursor position), if instead a gamepad or touch is used then the player face where it is going. I could have toggled this for melee since there is no need to aim with that.

Also adding some feedback when hitting an enemy would be super helpful

There is a little animation which is, as you told, possible to miss. Some friends of mine, while testing it, told me the same thing that it's a bit unclear when player actually hit. Maybe a sound could have been helpful.

it would be great to have a way to see the player's health

It is in the top left. It's hard to read because I choose a weird font to make a semi-futuristic weird HUD which looks cool :P but at the expense of readability. Not a good choice of mine, to be honest.

Thank you for playing the game and for the precious feedback.
Maybe we could team up for a jam sometime in the future, if you like.
