Thank you! The game can indeed be quite challenging for those who are not familiar with morse code. I plan to add stages that will allow for gradual learning.
I will try implementing a display for the timing of the Dah distinctions. It seems like a good idea to show the entered code in real-time before a character is inputted.
Currently, we rely on the movement of the sentence in the bottom right corner when words are distinguished, but adding sound effects seems like a good idea!
Thank you also for reporting the bug. I will consider adjusting the transparency of the catalog!
