Played all 10 levels, I can give some suggestions

You could add skulls that move but will probably need to indicate where they are with ripples in the water 

You should add variable scares when hitting the skull as it can get a little old to see the same one each time

The disappearing and reappearing skull mechanic makes it into a maze and memory game at the same time which isn't bad but there isn't any reason to not just wait around for them to reappear. Something things that could amp up the horror factor would be having the skulls watch you or start following you. It might be hard to balance how much time to give the player to memorize the maze with a time limit though. 

This was a really funny little game, and I liked it a lot. 

Things that worked well

• The "on/off" feature of the game which made me have to remember the path was really fun. It felt great when I remembered the path, and when I missed it, the fact that you just start over was good for me. Just the right amount of "punishment" 
• The "circle" at the end, for some reason, I feel that the visual structure of the game told me excatly what to do. The skulls are clear that I should avoid them, the rocks are also clear that I cannot go through them, and the circle indicates that I need to go there. 
• The music is nice, and fits the theme
• The story being told in the beginning of the game was nice

Things that could be improved and ideas

• The game is not saving my progress,  and it was annoying that I could not replay a level against my own time. When I went back to main menu to replay a previous run, I lost all my progress. 
• It would be nice with some soundeffects when you die and move 
• I dont know about the red color, I understand its purpose, it just feels a bit flat (this is probably just me)
• Some moving or more advanced pieces
• Some powerups that will allow you to jump out of the water and across rocks. Extra fish or something else that can be collected while playing. 
• A time pressure and maybe playing against a ghost fish or two to reach to goal first. 

thank you for sharing your game

If you have time to play my game and give it some feedback, I would really appresiate it :)
