Kernel Bug Cave Revision Concept

Once I rethought the color concept for an old game idea of my friend. What do you think, "resurrects"? 👀
In general, the game is still in early working condition, but it needed a visual overhaul, so I joined.
It's a 2D robot adventure platformer with lots of puzzles. You can learn more about the game here:

PS: Actually, the color of the rocks turned out to be different in the end, but this is just the very first version of the redesign
