Thanks for your feedback.
- I can lower the gravity of the bullets, but i want to have bullet time.
- I will add a feedback for crouching
- I don't think i will change the audio, because I want to give the sensation of space, with the music coming from the front. I will lower the volume of gun sounds. I didn't add too many audio settings because I worked on sound design for it to fit well on my game concept.
- This thing with "inverted" colors exists because before i added the yellow walls the easy was too easy, so i added some difficulty.
I want to know your opinion about the camera shake.
If you encounter more problems let me know, and i will find a workaround.
The update will come soon. :)
