Very fun and cute little game! I really love the concept and think it was very well executed. Your game had a very nice learning curve as well. Also, I'm not sure if this is intentional or if it's just a my-browser thing, but I did find a bug that makes the game way easier than intended.
When I click in one spot and then click in another spot somewhere else on the screen, it will sometimes draw a straight line between the points instantaneously, and consume very little ink. It doesn't distract too much from the experience, but does make the game significantly less difficult when it comes to getting 3 stars.
Nevertheless, great work! I really hope to see this game played on stream!
