Thank you very much for your kind words :) Your feedback is very helpful and I totally agree with you - a tutorial would have helped a lot and would have made things more clearer. For the footstep sound we used a sample of four different sounds but maybe they were too similar in the end. I really like the idea to distinguish between the two grass tiles though! Thank you very much that you took the time to give us so many suggestions, we will keep them in mind for the future :)
