The reason that combination looks good in Tron is because the cyan (and other bright colours) are used only as accents, they're never the main colour. In large quantities, colours that saturated will inevitably be painful to look at. Keep the cyan to accents only. Highlights, special glowy bits, things like that. Use milder colours for anything large.

I don't know what the gameplay is like in this game, but I would imagine the cyan lines would be confusing, since they seem to imply walls/paths that aren't there. I'd use a darker cyan colour and make a tileable pattern instead of just lines like that, so that it's clear that it's purely decorative. I say it should be darker because as it is now, those lines could easily overpower the units, making the game harder and more confusing to play. Use the bright cyan only on foreground elements, not the background.
