Didn't know that one.. Sounds very useable, thank you!

About unfreed memory - it's probably related to useage of 'parent' pointers (my guess), since I use them and on close they aren't removed probably. Got to make sure that I free/remove everything before closing the engine. I do that before loading new level or restarting the current one, so I just need to do that before exiting the game too.

Edit: nahh, I was wrong got to use 'sys_marker' and look for the leak.
