Thanks so much for checking out our game and taking the time to write such a thoughtful response.
We would love to love to add more levels in the future and to think a little more about the skill curve.
We're really glad you liked the artwork and that you found the game "calming" because that is exactly what we were going for as far as game play feel, so it's awesome to hear.
We have not heard of gdwc but it is definitely something we will look into, thanks for letting us know about it! :)
