I read that you intentionally made the text move at that speed, and I kinda get what you are trying to do. That's why it is very important to have a quiet time with yourself during these types of situations. Just take a couple of deep breaths, clear your mind and look for something good about it rather than focusing on the negatives.

Nice graphics, but Watching so many texts go so fast and having to answer fast makes it a bit stressful, If it had voice acting maybe it would be awesome.
