I have a wacom tablet, and i thought it would be cool to try and use it as the cursor, but i saw that the game doesn't take the input of the pen. I changed some settings, it would get the click input but not the stroke, so nothing would get clean, just move the cursor around. It would feel even more immersive by using the tablet, like you are actually cleaning the objects with the tools. But i saw that anyway later on the big part of the game is automized so it become less frequent you cleaning each piece one by one.
i know that 0,05% of people would actually use one for playing so if its hard to implement don't worry, the game is nice already, i just thought it would be a nice more immersive input
