You can't always predict everything when you release a game. :) I have an updated version of Errro with a couple of small enhancements.

Update - You can't always predict it on the second try, either. If you downloaded the source version update in the last couple of hours, please download it again. It fixes a crash bug in the level editor. Thanks!

Firstly, the new source version includes compatibility with Python 2.6. Previously, it only worked through Python 2.4. If I had updated my system in a more timely fashion, I would have worked this fix into the first version.

Also, both versions include the following fixes:

- A new "undo move" feature
- An option to run the game in fullscreen mode
- Fixes to 2 levels (later in the game) that make them easier possible
- Fix to the sound effect preference setting

Also, make sure to look at some of the new downloadable levels! I posted a screenshot of the newest such level; you can currently see it at the side.
