I've just released version 0.3 of 'Escape Made Easy (E.M.E.)'. You can download the update on the downloads page.

This update includes the following changes and fixes:

• The game no longer requires the ABGR8888 pixel format.
• Fixed flickering dialogs in the main menu.
• Fixed an in-game rendering issue where the game map was corrupted by the level up dialog.
• Fixed floor numbers in the "You are now on floor #x of the prison complex." messages.
• Added the ability to return to the previous floor. Note: both the previous and next floors are regenerated with new items and enemies. You will not receive a health bonus when returning to the previous floor, but you will receive a health bonus when returning to the next floor from a previous one.
