With Marbleous being a casual game with a simple playstyle, there was not much urgency to have a great deal of onboarding, as the player would understand the overall gameplay loop within a few levels. Future onboarding would have been implemented as new pieces were introduced that required new interactions from the player, if Marbleous was to be released as a full standalone game.

​

With Marbleous having such a simple control scheme and the game consisting of only a few levels, I felt as though it wasn't necessary to have a control's menu for players to refer back to, instead, the controls are taught to the player in specific levels within the game space; simple game, simple UI. For example, in the first level, the player is taught how to move pieces. Making the words Click and Drag have a bold style compared to the rest of the text gives these words a higher sense of priority against the rest of the text, allowing the player to understand what interaction is needed without necessarily reading the entire text. These instructions persist through each level they are presented in, so if the player were to fail a level, the intructions will still be there on their next attempt.
