Hey Daragard
Really glad you enjoyed the game! Thankyou so much for the thoughtful feedback.
There's some great solutions in your feedback and I agree this is an issue that needs to be worked on... The suggestion of arrows - perhaps via a compass like UI? Could be a helpful indicator... Also the shader graph idea - maybe a subtle indicator could work well...
Thinking of this I'm also thinking the maze / general level design needs to be worked on... some gaps in the rocks on those problem areas would mean as the waves go up and down you would be able to see the orientation of your boat.
Additionally yes - I think I know what you are talking about with the mouse input. I'm not certain of the issue at present but I have noticed that 'clicking' on the screen can help to reset the calculations of the 'virtual cursor'. Also coming out of full screen mode can cause the calcuations to go awry. I intended for the cursor to be 'locked' in the center of the visual space and for it's position to be 'virtual' so that these kind of issues wouldn't happen but I will take a closer look at the script and see if I can ensure for a more consistent sailing experience!
Hope you came back for further sailing and saved more souls!
Cheers,
Tom
