Sure. It was almost the last level so you played most of the demo. Thank you for playing and commenting.
You are correct about adding a warning and I'll do so (Added to the comment but I'll add to the game as well). I'm not sure how I can mitigate the issue. If I allow the user to pick a low contrast or maybe even change the colors from dark grey and light grey to 2 different colors with the same intensity it might solve it. I don't know enough about the subject, but I'll do my reserch.
Please let me know if you have ideas about it or the game in general. You played the grand majority of the game but I intended to make it a much longer game in the future that better use the mechanics. So if I can get good input early that would help a ton.
