Sorry for not playing the game, but watching the video the gates passing you seemed too intense an effect. Could it be more subtle, less distracting?
The video is not updated as often as the game itself, so it does not necessarily correspond to the latest version nor reflects the actual game play. The current version contains some adjustments on the intensity and color of the side barriers but those changes haven't been recorded on video yet, so please give it a try and if after playing it for a while you still think it requires more tuning I will gladly add it to my todo list. Thank you for your comments and hope to hear form you again.
