The game seems to freeze randomly but it seems to happen when you move your mouse around the touchpad at some specific situation.
Below is one example (use the savestate from http://www.sendspace.com/file/1o1agu\)
1. savestate loads at the left image
2. click the touchpad and the "3" will appear as in right image
3. move your mouse just when the "3" appear and the game will freeze (move sooner or after 3 appear, it will not freeze)
I think it is the same when you clear a stage where the stylus icon supposed to appear the word "CLEAR".
Nitsuja, you seems to be looking at input, touchpad etc. Maybe you are interested in this issue.

Is this a regression?
I do get random freeze in the past svn but did not drill down to this point - so I am not sure if it is a regression. In the past svn, it may jam the sound as well but that seems to have been fixed.
It seems this game has many random freeze points and it uses stylus/mouse to play the game.
