The following has been resolved;
- Loose Wagon's final boss could be controlled with the arrow keys.
- Invisible "block" that could destroy your bullet seemingly for no reason on NG+ during a boss fight.
- Some stage-confining collisions were not set right.
- Depending on your gamepad, using the joystick for movement could cause you to "lock up" when crouching.
Thank you everyone for your feedback and bug reports!
