At first I was like "what is this game, what I have to do?" I almost lost hope to discover what it is about. And then I've discovered that you can press R, G and B to do something with those crystals. Please add clear description that these are buttons, it's unclear otherwise!

I've completed the game, but I have no idea what I was doing :) Also inverted rotation added some difficulty, but when I figured out that you can ram cavern wall, clear the room and then ram another wall, rinse and repeat.

I'm sorry if anything is unclear. I put a lot of info in the description. I also apologize for the camera. This is my first time doing anything first person, let alone grid-based.

I don't understrand the goal. Need some tutorial. Good luck!

Yea the game is reallu disorientating the derationing feels of, how images are displayed in game feels way closer and off,  I have no idea what to do, and the music is simple.

I also cannot see anything about dualit

im also gonna guess how the camera looking is too close, andturning may be inverted, i feel like its inverted,

Super disorientating :/

Hah! I like the aesthetics! 

It's a bit hard to navigate though!

uhh... what? This game confused me so much.
Here is a small list of stuff that I didn't understood:
-> What is the objective? Am I suppose to collect the crystals? Touching them seems to do nothing. Is there a key I'm suppose to press?
-> At menu there is a drop down menu with words "small", "medium", and "large". What does that mean?
-> The camera turns so sharply its disorienting. I can't tell how much I've moved or where I am without constantly adjusting.

I'm not sure how to rate this game

Do you think you still have the time to implement some sort of step based movement? Seamless movement is normally not allowed.
