Thank you! I'm not one to make excuses, but the lack of puzzles were down to the limited time we had! I wanted to work on all my modules for the week not just TDEMO!
Given more time, I would definitely make more puzzles :D
The snakes do have different speeds as seen in Level 7, I just haven't really made a fast one yet! Maybe I'll try and do that when I come to developing the game for the google playstore.
