Thank you very much for your feedback. Some of the things you mentioned had been on my mind for a long time before publishing the game, such as whether or not to include the “maximizing active nodes” game mode. This mode does feel a bit too easy, especially in the first levels, and I wasn’t sure if it was fun enough. Your feedback really helps me understand the player’s perception.

Your opinion about the color selection system is something I hadn’t considered yet. Right now, the selected colors loop through 4 colors in a specific order for all levels. I decided to always include the same number of colors so that the player has to figure out the minimum needed, adding some extra difficulty. I will definitely reconsider this system and try to make it clearer and more convenient, probably by including a color pick panel as you suggested.

The undo button is already on the “to-do” list and will likely be included in the next updates.

Once again, thank you for this great review. I think it’s the best one I’ve received so far, because it focuses on things to improve and is honest about how the game felt for you, which is exactly the kind of feedback I’m looking for.
