If you'd like any tips then work on your basics first:
Your mineral formations are very inefficient.
Ramps have probably not been post-edited (check terrain levels for vision bugs!).
Overall there is not much concept here and the map is probably oversized (hardly any 2p map requires a 128² format).
There's also a relative shortage of gas.
And gas issue (inefficient gas mining due to geyser position) in the bottom main.

1) Agreed, it's kind of... on purpose, but easily adjustable.

2) Already done

3) Is there a huge difference between 128x128 and 128x112? It would play kind of like a cross spawn 4p.

4) A gas could easily be added at the non-island 6 & 12, but I feel like 5 gas per player is relatively OK (cross game)

5) Should the geyser go on top?

I modified several elements:

1) Map is now 128x112
2) Mineral layouts reworked
3) Mineral count reworked, mineral only removed.
4) Geyser positions reworked


I think I got the highground/lowground and pathfinding regions right, but I'm not 100% sure about it.
