Yeah, I should've done better on the instructions and I realized mid-way that the repeated clicking isn't good, so I made an auto-scan feature but it might have been too little too late.
The clear only clears the screen. The submarine on the radar doesn't rotate. If the submarine is thrusting into a wall, rotation doesn't work. Rotating and thrusting are toggle buttons, not presses. But yeah I should have written clearer instructions and playtested more.
Thanks for playing!
