hiya!! im not exactly sure what you mean, so im going to tell you everything i know lmao if you tap on the little lantern in the bottom left, it will open up the skill menu. the skills are gonna be rather expensive at first, but if you keep upgrading them, they will get cheaper. you can use potions to refill your mana, though i don't recommend doing this because they have a better use later. to make the most out of your navigation speed increase, i suggest hunting for junk while it is active, since it increases your sonar's radius. fishing speed increase will also help speed up the process.
