You are a patrol boat from a small fishing village.
Use the navigation lights and your foghorn to find the ships you must control.
Look at the lights and the azimuth will be drawn on the map.
Sound your horn and boats within hearing distance will respond. 

Controls:

Use WASD to move, space to jump.
In steering mode, WS controls throttle and AD steering, Q and E can hold the steering in place.
Shift to run or move controls faster. Z to zoom.
Hold I (i not L) to use the ignition and start the engine.
X can be used to go to neutral and M to hold the map.
I forgot to add a button for the horn, so it is mouse only. 

Q/A:

Q: Did you spend the entire jam creating random mechanics and only added rushed gameplay on the final day?
A: Unfortunately yes.
