Gotta say, this is really impressive! Your game stands out for a number of reasons.
Setting - it's really refreshing to see an 80s VHS style dystopian future in an RPG Maker game. It's clearly inspired by Robocop, Blade Runner, and dare I say there's a little Lethal Weapon in there? It certainly makes a change from the fantasy and sci-fi worlds!
Aesthetic - the effects you're using are well implemented and really help to sell that 80s VHS vibe I mentioned earlier. It's reminding me of Hotline Miami, Far Cry 3: Blood Dragon, and (to an extent) Retro City Rampage in a very good way.
Battles - you've taken a tired first person battle system and made it quite interesting by making it resemble a first person shooter like Doom, Quake, or Wolfenstein.
This is actually something I'd genuinely consider buying on Steam. The only thing I could really suggest to improve would be some of the sprites and walking animations. I always appreciate the effort placed into making custom graphics, so major props for taking the time to do that. You even put in a lot of little touches, like the animated neon light signs, however it's let down by awkward stiff walking animations. It looks like you're using a plugin for extra frames, which will give you smoother animations, but the frames themselves are lacking.
How do I explain this? I'm not getting a sense of movement from them. It's less like a walk and more like an awkward shuffle. It would work great for a zombie's walk cycle but for a bad ass clad in leather... not so much. I think the main issue is the legs never bend at the knee, it looks like the legs are straight at all times. There needs to be a sense of weight to it, a commanding presence, more exaggerated and clearer movement of each leg. Sometimes moving the torso and head down a couple of pixels can help sell it as it gives the animation a "bounce", similar to how the sword moving with the arms really sells the idea the shoulders are moving. Definitely something to play around with.
The guards in white in the battle screenshot could also use some touch ups. Their arms seem very bendy as there's no clear hard elbow. Take a look at an anatomy book or website and they should have examples of how the arm bends. The clothing also looks to be pillow shaded (even amount of shading on each side) with nothing to give a hint of what material the clothes are made out of or where the folds might be.
Finally, there's a lack of shades on many objects - especially cars - that make them look flat rather than 3D. This kind of kills the believability of the world a little for me but is thankfully an easy fix by just going in and shading them a little. In some cases, it's more a lack of detail, such as the shop keeper, that prevents the sprite art from selling it to me.
The fact that I have to be that specific and am taking time to say how I think these issues can be fixed tells me I really like what you have here and I'm excited for it to be the best it can be. I'd love to try a demo of this once one's available and I hope I didn't overstep any boundaries.
