Please don't publish test builds.
You can check *exactly* how the game would look like if published with the 'Preview' feature.
Since you didn't include even a hint of the future game's features, I can't tell what can be considered a bug.
You can stick to all surfaces, even the ceiling and perform a sort of quasi-double-jump (you can jump again when you fall, but not when you jump from the ground). That looks buggy (you should either always be able to double-jump, or not at all). Not sure if "sticking to walls and ceilings" is supposed to be a part of the final game, too.
Well, good luck with the game, but in the future, please don't publish versions which do not offer any gameplay. If you need someone to check it before release, you can post a link to the preview in Game Development forum and I'm sure people will be happy to help.
