The name is "No Remake" as it is a remake; much like LAME (an mp3 encoder) is called "Lame Ain't an MP3 Encoder". The most recent addition to the engine is having "special effects", where objects can dissolve in real-time.
The effects are all generated using the same shaders. It runs on OpenGL 3, but the effects would run on 2.x too as they only use vertex and fragment shaders. They appear on the shadow maps too, as you can see.
This looks really good. Nice improvement.
Two small pieces of advice. Make the artwork for you:
In this case you could use different shaped platforms, to allow players to quickly see what turret is what without zooming in. Even if just simple shapes; in fact using simple shapes as a foundation is a great idea.
Second, use references:
Even professional artist uses references. Lots of artist use simple shapes to make complex art. https://www.deviantart.com/tugodoomer/art/env-obj-52-573913173 Looking at their work should inspire some of your own ideas.
I Like the depth of the platforms and your roundness looks visually correct. Good work.
