Update 0.5.1a

Finally, after many days of testing and working closely with our fantastic community, we found and eradicated the "boss-fight crash" issue. Some users who previously couldn't terminate the raid can now play a complete run. Also, the key-binding features have better compatibility with the Numpad. With the Block num activated or not, you can use it in your configuration. [h2]Changelog 0.5.1a[/h2] [list] [*] resolved the "boss-fight crash" issue. [*] improved key-mapping.
