The game won't start when i press play on steam

When I was running/ playing the first beginners game that gives instructions, I came to a place between cells where my player got stuck on the side of a platform. I suggest getting the code right so that this doesn't happen in ANY game. Character won't jump, won't move. Now must start over. This was the very first time I ran the engine-- so it's not a great impression to leave to new users. Thanks....

Here I've compiled solutions to bugs.

Here is my youtube channel that I do every 2 weeks on how the development is going as well as community stuff. https://www.youtube.com/watch?v=cZXuH7zWLC0

Is Unfolding intended to be an actual game engine focused on an specific genre ala RPGMaker or a creation game like Little Big Planet/Mario Maker? The name tells me the former, but the videos the later, so which is it? Are people supposed to, eventually, be able to use the engine to make stand alone games or will they always be tied to unfolding?...
