0.0.3

This one is much smaller, compared to the last one, but it is still quite important. I've made some adjustments to a bunch of things: player's oxygen, dialog, sound effects, enemies, quality of life features and etc. I have also fixed some minor and major bugs. One change makes finding one of the secret bosses easier.  Hopefully someone will stumble upon it.

I'll start working on some major updates very soon, probably going to spice up the combat system. But for now, I hope my 3 players will enjoy the update.
