I understand that the author wants to make the mermaid's survival journey very difficult, but the game controls are not "difficult", but "disgusting". The camera rotation is very difficult, which often causes me to flail around in corners like a dying fish, and I have encountered several situations where I get stuck in the model and cannot get out. In this state, I cannot jump into the water.
If you want more people to play this game, please make sure to modify it.
