The gameplay seems like it could be very fun. The gun is satisfying to use and the levels are pretty well designed. There one thing holding it back though: The jump physics. You have little air friction (if any) so trying to move while jumping feels like being on ice. The jump height is also fixed (as opposed being able to release the jump button for a lower jump). This isn't too bad in some games, but in this one - where you're constantly jumping to dodge projectiles and fight enemies at different elevations - it's glaring omission.
That complaint out of the way, I love the presentation in this game! The cyperpunk aesthetic is super cool, and utilised well. The art in general is very well done, as is the animation for everything. The music also helps to give it that cyperpunk flair. One bit of the presentation that stood out was the hud bar. It's very detailed, but also very readable. I like the little meter for the gun capacity. Having a mini-map built until the hud is really cool, and something I don't see a lot of - even in commercial metroidvanias!
