Improved the kana typing keyboard remapping, made the game start in
fullscreen by default on Retina macs (due to performance issues in windowed
Sunday, May 6
A minor release: support for custom keyboard remapping for kana typing,
using a configuration file. If this works well for the people who need it,
I'll set it up for more general keyboard remapping.
Saturday, April 28
Put out a release to fix some annoyances. Working on something bigger.
Thursday, March 22
Bug fix release today. Some of the latest changes didn't work properly,
including a crash bug. Should be better now.
Saturday, March 17
New version out today. I think this improves a lot on the training
usefulness and general enjoyability. One of the most obvious changes is

to make progress through the caves.
The update mailing list has been reactivated (you can sign up for it on
this page or in account configuration in the member area). I've fixed some of
the technical stuff that was a problem for spam filtering, so hopefully this
should stay available.
