Unique idea. I like how the humans and goblins have different rules for their turns. It doesn't feel like there is much to do besides "try to rig it for the humans" or "try to rig it for the goblins". Maybe if this were a mechanic of a regular SRPG, where your goal is to get a certain team to win in each level. But then there would need to be pros and cons for each decision, as opposed to (for example) trying to get the humans to win by just doing the minimum number of goblins turn. There would have to be some benefit to giving the other side more turns, like maybe it'd make your characters stronger if they have more time between turns? Would be interested to see this idea expanded on.
