Our apps wouldn't be possible without the contributions of some very talented people and valuable resources. We'd especially like to thank the following:
Many of the illustrations used on our 3-Letter- and 4-Letter-Word apps are courtesy of the wonderfully talented folks at freepik.com.
Sound effects courtesy of freesfx.co.uk.
Music courtesy of the extremely talented and generous Benjamin Tissot. Check his work out at bensound.com.
