If you get tired of the original levels you can always make your own. You can create your own levels with the included editor.
A level is divided in different blocks, as you can see in the screen below. Each block can have different shapes, for example a circle or triangle. All blocks have a background material, and if the block isn't "simple" it also have a foreground material. The materials can be grass, iron, sand (the ball can roll on these three), tree (wall), water or hole. You can lean several of the materials to create hills.
This might be confusing, but try the editor so will you learn it quickly.
In the edit menu are more tools you can use to create levels. You can for example rotate the whole levels, or create a random level.
Save
When you save a level you must save it in the folder "Levels" that is in the Floginim folder. You can place it in a subfolder; Floginim will read all files and folders when the games start. So you has to restart Floginim to use your new level. If you have created a course and change a level that is in that course, then you have to add it in the course again.
