I just released update 1.0.40! The change log is as follows:
[list]
[*]Improved Dead-Zone handling (controllers)
[*]Added Cursor Sensitivity option (controllers)
[*]Added Dead-Zone size option (controllers)
[*]Added play tutorial prompt for new players
[*]Allowed multiple events per cell (bugfix)
[*]Killed events on touch heart (bugfix)
[*]Other minor bugfixes
[/list]
So, for those of you who have been having trouble playing with a controller and switched to keyboard/mouse, I'd give the controller another try and change the cursor sensitivity and dead zone settings as appropriate for your controller. Also, if you haven't, play through the tutorial with the controller, as it will show you a few shortcuts that make it easier to do common actions without moving the cursor.
