A strategy game where your units must reach a certain objective (could be a set number of steps/a destination/ an item).
Units move automatically after the round starts.
You have to build a way for them to do so.
Each one of them responds differently to buildings/ other units.
Depending on how you build units might clash or not complete their objective.

Each level would have a different layout and there would be certain amount of buildings one can use.
Lots of room for adding complexity.
