Pressing and holding a keyboard or mouse key for a long time will cause motion or action to continue after releasing the keyboard or mouse key. For example, running forward with W for a few seconds will cause the character to continue for several blocks when W is released. In short bursts it is OK. This makes it risky to travel around dangerous places. Right click actions like using the bow sometimes don't work.

This issues only started for me with 0.14.1. Yes, 0.14.1 does exist in spite the create bug UI complaining that it doesn't. I see the version number right on the corner of the Play screen.
