I made one about a year ago, originally it was a multiplayer map but has since been changed to single player due to some of the concepts used and the importance of single units in some scenarios couples with potential delay/latency issues with that.
A decent player should be able to get through the first stages.Possibly the ones most likely to go wrong are the ultralisk/dark archon stage and the bc/arbiter stage.The final stage i have not been able to beat but i have tried maybe only 6 times (tested triggers with cheats).I think the best strategy is destroying both enemies cc/nexus straight up otherwise their macro may overrun you and cause timeout.
If you have some spare time dl here

Report bugs here or in pm but should all be fine.
