A puzzle game for those who get a lot of satisfaction from cleaning something.
Objective
Clean the whole field.
Input/Action
Tap a certain row or column. A broom will slide across it and clean the whole row/column.
You can tap those from both sides. This can make a difference! Because something might block or deflect the broom halfway.
For example, each row has an arrow to the left and to the right. Tap one of them to execute the action.
Map
The field starts with lots of dirty spots. You can do something to clean them (swipe, draw a line, tap to activate some machine, slide a broom across).
Of course, there are different brooms, and there are things in the field that stop them. (Actual solid walls, special teleporters or deflectors, etc.)
These brooms are shown at the start, in sequence. You don’t pick one yourself, as it’d require extra UI and buttons.
