The feedback so far has been overwhelmingly "I can not pass the calibration scene, no matter what", which, while frustrating for me (but probably not as frustrating as it was for those who were stuck in the room and kept gesticulating around) means I had to rethink the whole approach to magic.
The next version still has the same mechanics for spells, but now there are "guides" showing you how your hands should move in order to cast the spell. Apart from making casting *much* easier it also looks quite cool, so I am quite pleased with it so far. I still need to tweak a few lose ends, but a release on the March, 12th (my time zone) seems realistic.
cheers,
Sammy
