Multipoint Polygon Collision Physics Issue

Hi Construct team,

First, I like to Thank for your great effort and tool you created.

Here is my issue with the Polygon Collision mask. I'm creating a circle maze game, the maze has multiple points in polygon collision mask. A ball in the maze will roll according to mobile Accelerometer input. But the ball comes out of the maze even there is a collision mask. Pls, download the file from below path. Play it in mobile Construct. I have marked the issue happening area. Pls, suggest me where I am going wrong.

Using more than 8 points to form your collision polygon is the mistake.

A dialog popped up on the moment you added the 9th point and you chose to ignore it.

Instead of a single image, compose your labyrinth of several rectangles and other, each with a simple collision polygon under 8 points.

Separate the various walls of your labyrinth and add them as instances to your project.

Thanks for reply Kyatric. I will try it and let you know
