Thanks for the feedback. :)
I really appreciate that you noticed the small detail with the neon-aesthetics, since it was a conscious effort from my part, even if it might seem like a lazy way of doing it.
I like your ideas of having a cleaner intro/outro menu and adding black to the background of the text. And you're totally right that it was mainly due to time constraints that lead to the unpolished nature of such things. I also like your idea of adding feedback to the player for turning the cube. It was also something that I had in mind, but didn't get the time to add it. In that regard, I really liked the feedback that was in your game.
