What a nice game. I saw your interview with Amanuesis and had to give it a go myself. Though a few hiccups here and there, the game is fun and very enjoyable! I gotta give you kudos for the music and audio in general, very satisfying and comfortable to listen to.
If you're planning on updating this project, I'd love to have a dedicated button for the secondary painting, brings a lot of speed to gameplay. Though I don't know if it aligns with your vision.
Anyway, great job! Love to see such nice projects!
