 Implement the [Chaikin's](http://graphics.cs.ucdavis.edu/education/CAGDNotes/Chaikins-Algorithm/Chaikins-Algorithm.html) algorithm step by step in an animation.
 
-The objective is to create a canvas where the user will draw 1 or more points, and then the screen will play an animation of each step to get to the final result of a curve drawn using the `Chaikin's` algorithm. You can see [here](https://youtu.be/PbB2eKnA2QI) a demo of how the application should work.
+The objective is to create a canvas where the user will be able to draw 1 or more points on it, and then the screen will play an animation of each step that is taken to obtain the final result of a drawn curve. The animation must play for 7 steps and then it must restart.
+
+It is mandatory to use the `Chaikin's` algorithm.

 - Functionality:
 
-  - The canvas should receive input from the mouse: the user of the program should be able to use the left button to select the control point for the `Chaikin's` algorithm
+  - The canvas should receive input from the mouse:
+    - The user of the program should be able to use the left button to select the control point for the `Chaikin's` algorithm.
+    
+  - The selected points must be visible in the canvas, so you will have to draw a small circle surrounding the selected points.
+
+  - After pressing `Enter` the program should start the animation of the steps until reaching the 7th step of the `Chaikin's` algorithm. After the 7th step the program must restart.
+
+  - If the canvas only has only one control point, the program must only present that point and do no change at all.
 
-  - After pressing `Return` should start the animation of the steps until reaching the 7th step of the `Chaikin's` algorithm.
+  - If the canvas has only two control points, the program must draw a straight line.
 
   - Pressing `Escape` should quit the window.
 
 ### Note
 
-You are free to use any library for creating and handling window creation, rendering, keyboard and mouse events.
