Thank you! I installed it fine from Extras-Devel using the Application Manager. The graphics are a little nicer than PyRunner's, actually. The options are a step up as well as PyRunner has no options menu. And Scavenger allows you to map your movement keys, which is crucial to playability. IIRC, the N800 has a D-Pad to the left of the screen, the N810 has a D-Pad to the left of its hardware keyboard, and the N900 has arrow keys on the right side of its keyboard. So comfortable keys for digging might be in a different place for each device!

The main problem I discovered is that, when I run it, no icon is created for the game in the area where icons for running programs are displayed. When I press the swap button to change between apps or view the desktop, the game just disappears and there is no apparent way to switch back to it. I can see it in the list of processes, though (and kill it, so it doesn't just drain down the battery).
