Credits and license of the graphics are fine, but the tdc_lose.wav sound doesn't have a license. What is its license? Remember that all assets must be under a license compatible with CC BY-NC-SA 4.0.
It would be nice if the microgame played some music before losing too. The template now has a library of music jingles to choose from, and a way to make your game match the tempo (more info).
