The demo is updated to version 0.2.5.

• Optional tutorial level.
• New look for player character, courtesy of Kyle McArthur. https://rolltonotdie.deviantart.com/
• Experimental screen rotation on PCs. Enables portrait orientation, a.k.a. 縦 (tate). 
  • Run in command line with the following option. R = clockwise rotation in degrees.
    • --rotation R
  • Rotation is also possible using your OS display settings, but this option can be more convenient than manual setting and resetting.
• Fixed controller d-pads not working if they were read as hat switches.
• Stage-end bonus for any excess companions.
• Some balance tweaks.
• Minor visual frills.
