Hello dezm0n. Thanks for your comment.
I'm currently working on dialogue for special item pick-ups. This way everyone can understand their meaning. I'm happy you found the egg! I will be hiding 1-2 more in the near future.
The visual line flickering will not appear in a pixel perfect setting. For instance, full screen mode. A full final build in the future will not contain the visual flickering because the game will be downloadable and force specific resolutions by default.
