Thank you for liking this game! Getting stuck inside an object is a bug with Bakin engine. I submitted the bug in the forum a long time ago but even the team finds it hard to fix. Once it happens, the only way to get out is to use the blue return icon in Main Menu. When falling from a height, this bug is very likely to happen. If you could fly or use the paraglider when you are near the landing spot, you can avoid the bug :)
