Thanks for creating this tutorial. For me a fun way to get familiar with KorGE 
Some feedback:
- Step 0 is quite short and only setting up, when I reached the end it states: "In the next part of the tutorial, we'll know how to use graphics and text views and how to position them... ... Stay tuned!". At first I was a bit disappointed. I wanted to start with the fun part, but this was already the end. But after some googling I found the step 1 fortunately. I think it would be nice to add a link to the next step at the end. So that the reader easily can continue.
- In step 1 I had trouble getting the copied code regarding
roundRectworking, but it looks like you already have updated this part.
