Yes! I love those classic PC isometric games, glad you liked the look of it.
I had to play around a lot with the visuals until I could get the right feel, but I kept the models fairly low poly and created 2 or 3 textures via shaders that I could adjust settings on for different objects, so that they had some consistency.
Then I did some reading & watching to learn how to create a post-processing effect to simulate a resolution of choice - that way both the models and particle effects have that look to it.
For the particle effects, I kept to using quads to give it a pixely-feel, though I think the death effect could have been worked on a little more as it might look a little too modern. Something that I ran out of time on and couldn't quite figure out was how to get the button prompt icon to look a little lower res. If I had time, I probably would have just made it a low pixel-count sprite.
Thanks for all your feedback!
