I'm really sorry for that, several people reported nausea while playing, but I'm not sure how to help with that. I put an adjustable "field of view" and you can change the "stroke" effect for something less violent. Maybe it's linked to all the bright white on the screen, so lowering brightness may help. I may add an "inverted color" mode in the future, so the screen would be mostly black, or even let the player choose the color scheme. Thank you for your feedback.
