 	For one, it doesn't use any of the complex compat layers, it just directly subclasses Activity.  
 	Second, it uses only two basic UI elements (TextView and LinearLayout), and yes these are  
 	the only ones implemented (and partially at that, only the absolutely required functionality).

+Q:  
+	ok, so this can sorta run Gravity Defied. What's the catch?  
+
+A:  
+	well, first things first, technically I compiled Gravity Defied myself and removed  
+	some bug-reporting-init-related code which I got frustrated with stubbing out. however,  
+	adding more stubs should make that unnecessary.  
+	now for the second issue: `./data/` contains some stuff that should instead be read from the apk,  
+	and some of this stuff is also externally converted (e.g Xml from binary form to actual Xml).  
+	obviously this is not ideal for user experience. NOTE: it seems that the binary form *might* be  
+	protobuf-based, which would make reading it directly easier.  
+	and the third issue: Gravity Defied is still extremely simple compared to most android apps,  
+	doesn't acknowledge compat layers, and the most intricate UI element is completely custom drawn  
+	using the canvas interface, in a manner that makes it easy to implement with cairo.
 
 ##### Roadmap:
 
-first we need to gather a lot of volunteers, because the android abi is *huge*  
+- fix issues mention above
 
-then we need to settle on language / UI toolkit.  
+- fix ugly hacks
 
-I would like to shim stuff to C for performance, and use GTK 4 for UI - because  
-that seems like a lot of fun, and we need to be honest with ourselves, why  
-would anyone help with this project if not for fun ;)  
+- implement more stuff (there is a lot of it, and it won't get done if nobody helps... ideally pick a simple-ish application and stub/implement stuff until it works)
 
-__UPDATE__:
-
-- Started work on shimming stuff to C
-- Use Gtk4 for displaying the app's GUI (see screenshot.png)
+- integrate e.g. https://github.com/Cloudef/android2gnulinux/ for loading libraries linked against bionic; if we're lucky, 
+we might be able to get quite a few apps running that are 99% native, since they hopefully only use a few Java APIs and might not even complain too much if most of those APIs are stubbed
