Chapter 11 is available.
It's placed below Chapter 7.
Level update:
9-? is moved to 11-?, as it fits in chapter 11's concept.
A new level is placed at 9-?.
(Sorry, I am out of ideas on these levels.)
Future plan:
Mac and Linux build: In a few weeks.
Android build: In a few months.
Workshop support: Please tell me if you want to make custom levels for this game.
I'm considering if Steam Workshop support is necessary.
More chapters: when I come up with the right idea.
Other:
More than 1000 copies of this game have been sold at the moment.
Thank you for your support.
