I like how easy it is to use, you can easily create your own game or challenge for people in their teams using pointagraphs which are points given out when someone does something good (like completing an assignment). It's also very simple to change things around as well if needed. There isn't much room customization at this time but they have added more options since my last update so hopefully we'll see some improvements soon. This program has been great because of its ease of creating challenges/games with other students who may not be familiar with coding yet. We've created several games together including one where there was only 1 person left after doing all the work required within 30 minutes while everyone else watched us play each others' games during our breaks from class - pretty fun :D.
