 # Ecosystem Simulation
 
-A simple ecosystem simulation written in Flutter.
+A simple ecosystem simulation fully written from scratch in Dart.
+It uses the Flutter rendering engine with low level api calls.
+
+Warning for Windows users: There seems to be a platform specific issue where the performance of the simulation is very slow, but only on Windows. This might be related to the fact, that Windows does not use the new Impeller Rendering engine (this would mean that Linux is also affected by this issue, I did not test Linux). Or it's caused by some bug from Flutter that only affects the Windows platform.
+
+Supported and tested: macOS, iOS & Android.
