Hello! Thank you very much for your feedback, it's always a pleasure to discuss topics that I like!
Discovering great artists and sharing them is one of my joy, so I'm super happy that you liked Lenka and Michael's art.
Seeing you enjoy my music really makes me feel that games are a great way to share it. I occasionally publish short albums online but I like it even more when the music serves a story and mood. Also thanks for trying to make something out of the dots!! :)
The styles I was after for these letters drawing are typewriters drawing and calligrams. You're right about ASCII art, sometimes subgenred as PETSCII for C64 characters for instance (which also include basic geometric shapes). Generally speaking, the "correct" term is textmode art. Great artists for these are Polyducks or MrMo who work with geometric-like characters.
If you'd like to see me exploring this style, I suggest you'd check out my games Nature, Vignette of the ocean and No wizard where I worked with extra constraints.
No matter the choice, as a visual artist, I purposely select such crude representations to suggest rather than show, and let the player's imagination work. That's why graphics are particular in all my text-based games.
Thanks again!
