is there anyway to raise the supply limit to above 200? it would be helpful if you could.

We have tutorials for everything!

That one might be a bit outdated though, seeing as several patches have come out since then.

Otherwise, hero units take up no population; it may be an option to replace some normal units with hero ones

Or combining different races gives effectively up to 600 supply over three races.
