I did not have the same experience as the others who have commented, so it's probably all due to user error. I thought I would be able to change the color of the ink since there are the RGB dots on the jar of ink, but either I had the wrong tool or they don't actually do anything. I felt like the game just kept taking my money when I was trying to refill my ink without actually giving me anything. I clicked on the refill price button, the black meter above it, and the RGB ink jar. Eventually the bar would fill up, but the bar near the paint disable button would still be empty. I don't know what I was doing wrong. Also, when I clicked the little black square near the refill price button, a translucent black square appeared on the top left corner of the paper but didn't seem to really do anything. I think the concept is there, but the implementation could use a bit more polish. Or maybe I need to watch someone else playing so I understand how to play. 😅

The rgb dot was use just as visual and doing reference to color, my bad for that.
Refill the ink cost a bit (25) and refill only the jar connect to it, to refill the pen you need to guide the pen to the jar (later you can unlock a button to refill the pen directly). The black square near the refill button is use to change the ink from the jar but you need to purchased them at the shop. If it's empty it's because none were purchased.
Almost everyone failed or struggle to get the game controls, i really failed to get the player to understand how things work but well, now i know why tutorial are really important even if we skip them most of the time XD. The user error you have experience is due to me not guiding the user through the first step, if my reply help and you have time don't hesitate to try again to reevaluate my game
Thanks for playing and sorry for the inconvenience
