This was so much fun to play. I can see why people might be frustrated, but honestly the difficulty was a delight. I'm looking for morse code games to help me practice, and a lot of them are either way too easy or way too advanced for me. When it sank in how the game worked, I actually went "oh shit" and rushed to get my headphones so I could fully focus on the game. This reminds me of those old typing games. Samuel's voice line playing every time you have to start over was a really nice touch.
Also opening up the game's readme file and seeing this
was hilarious.
