So the name was something like warper or jumper or maybe something else.

The mc has a power he got from eating a rabbit and it’s considered a stronger power than normal it lets him basically teleport short distances. And he’s put into a maze where he fights this overpowered scarecrow that nearly kills him. Then later on he fights other people with powers or not on rafts and that arc ends with him killing a sea monster and getting an achievement.
