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.

Are we aloud to sell our games using this software or only share them?

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
