So right now this game is a prototype. It is my first game I coded myself. I've gotten bored of working on it and haven't continued in a while. I will come back to it soon. I want some feedback. I want some ideas for monsters, features, and other cool things as well as changes.

Here are things that I most certainley will add in the full release if I continue it:
A good menu
A creature editor (It replaces one normal creature when turned one, you can adjust it's speed, size, volume, and how close it gets when you reset oxygen)
Submarine editor (Unlocked when you beat the game. Adjust turn speed, move speed, if the camera scanner is live, hp, and oxygen length)

1 special monster that will always spawn in.

4 special monsters that replace one normal one (including yours if enabled)
