I really like the sketchy, chalkboard-like style of your game! I'm also a solo developer who wants to keep making games, though as a hobby rather than for money. I already have five games (four made for game jams, three of which were made as part of a team) and my current project is a grayscale, character-driven point-and-click/visual novel hybrid about a bored shapeshifting anomaly that seeks to understand humanity, then exploit it for pleasure.
Wishing you the best of luck with your endeavours :D
