Made in Construct 2 this is an update to a previous version I made a few years ago.
Click the options menu and set to play against the cpu or select 2 player mode. You can also choose to play against the clock, full screen mode, audio on or off. I added local storage to save the current configuration of the game it should load up where you left off in the last session.
Play against the cpu - left click and drag to move the ships around the grid, right click to rotate, click launch when ready.
Play in 2 player mode - player 1 position ships when ready click launch, player 2 position ships click launch when ready to play the game.
