I've published an update on Google Play, version 2.5.0.06. Your old savegames will not work, also it now requires 1Gb RAM (it never really worked on devices with 512Mb RAM anyway), and it will download 1Gb data from the net (it will remove old data files, and you cannot disable downloading, sorry. If you want to put your own data files - let it download once, then replace files on SD card).
There are bunch of improvements, I'm most proud of the fix for properly restoring it from the background.
The mouse is now in the tablet mode by default, you can enable relative movement/laptop mode from SDL menu.
Google Play pageAndroid package fileEdit: and the very first review is that it won't run on the Galaxy Tab 2, with 687 Mb RAM - the user got scared with warning dialog (SDL reads /proc/meminfo to get that number, and it may vary on different devices and even different ROMs, because some part of RAM is used for kernel and GL textures), however I'm pretty much sure it will run, the mem usage on my device was under 400 Mb even on large maps. So I've updated it to version 2.5.0.07, the only change is that it will show warning, when there's less than 640 Mb total RAM. Also, you may now disable downloads by killing process, launching it again, going to SDL menu and unchecking all checkboxes inside downloads dialog.
