Incremental description

'Incremental' is a new defense strategy turn-based game, on a chess like board.
The objective of the game is to defend your base as long as you can.

On each turn you can only create a new unit or change the direction of one existing unit.
Units will continue to move in the initial direction until a new direction is selected.
When different units meet up there will be a battle and the strongest one will survive.
When friendly units meet up they will merge into one and continue in the direction of the strongest one.
Each turn, the strength of all moving units is increased by '+1', including the base unit.
When your units move outside the board (are on the edge) their strength will decrease by one each turn.
General RULES
- All moving units get '+1' strength every turn (including the base unit)
- When your units try to move outside the board their strength will get decreased by'-1' (except unit on base)
- Units will continue to move in the initial direction until a new direction is selected
- If you command unit to move, it will not stop until it hit the wall.
