Version 1.0.0.1 was released today.
The changes are as below.

- Corrected issues related to actions and hit-detection.
- Added the screen resolution 1440p to LAUNCH OPTIONS.
When 1440p is specified in LAUNCH OPTIONS, the rendering resolution is 2560 x 1440.
- On the first startup, the game now enters Fullscreen Mode.
- Pressing Alt + Enter now switches between Fullscreen Mode and Windowed Mode.
- The mouse cursor is no longer displayed when in Fullscreen Mode.
- When in Windowed Mode, closing the window now ends the app.
- The game now saves whether you used Windowed or Fullscreen mode, and enters the mode on the next startup.
- The app can now be ended from the pause menu.
- Other minor issues were corrected.

We plan to add graphics options in a future update.
