GrannyC: I'm terribly sorry

The latest episode is indeed mostly mouse controlled, but you can still control 90% of the game with the keyboard. Walking with directional arrows and interacting with objects with the enter/space key are unchanged and should work as they used to.
Aside from accessing the main menu with the Escape key, all menus and battles are still controllable by the keyboard as well, yet be sure to keep the mouse cursor away from any of the current windows or it can interfere (if you're not playing in full screen, you can simply move the mouse cursor completely off the screen).
The one thing you can't do with the keyboard is have direct access to access the main menu with the Escape Key as the previous episodes did. To access the main menu, you must use the mouse (by moving the cursor towards the top of the screen and the pop-up menu will appear, which looks like this:

I'm sorry for changing the controls around on you, and I'm doing my best to keep everyone's control schemes happy. Putting in a control scheme option in the options menu like you suggested is a wonderful idea! So I will do my best to put that into the next episode.
However, if it's a deal breaker for the game, I completely understand and I'll be happy to give you a refund if you wish. Just shoot an email to
support@jaybot7.com and I'll do so as soon as possible.
