Goongeon update

Hi. We have fixed the things has been reported:

1. Enhanced wall-jump #1: The behavior was not correct with analog joystick.
2. Enhanced wall-jump #2: Now it's more enjoyable
3. Invisible spikes. In one of the updates, we forgot to put the spike sprites in an area, but they have been added now.
4. Map: The resources of the map were not exported in the build. Now it works.

Thanks a lot for playing, comment and report bugs.

Have a nice day! :)
