I like that it's easy to use and understand. It has great tutorials to get you up and running quickly and also provides lots of help if you get stuck. You can export an HTML5 version for mobile apps or web sites. The experience feels too basic at this point. I'd like more interactivity with some types of assets (like cubes) and maybe more options in the UI. This could be a good option for someone starting out, but the price is a bit high for what you're getting. We are using it as a frontend for our own Unity game engine and have been able to build a couple of experiences so far.
