Maybe you could make the submarine move faster. But nice work! You can play my game if you want: https://itch.io/jam/-pixel-game-jam-2024/rate/2718966

Not bad, the controls felt a little sluggish, I feel like the sub could have been a bit faster.

I'm not quite sure what to do after I've collected the first three?
I don't quite understand why keyboard control and mouse click, I think it would be more coherent to click on some E,
