Thank you for your feedback.
Yeah I suppose I made the map quite big and complex, I'll keep that in mind and make the map simpler for my next project if I ever make something like this again.
Also are you sure you really got stuck? The player can jump 3 blocks high - and can reach 3 block high ledge that is around 5 blocks away. To get out from the bottom left part there should be a ledge and some islands that can be used to the top left of that section. Perhaps I should give some hints of that for future players.
As for the bouncing... I'm trying to fix the problem. Hopefully I can fix this soon... If not I'll be using a different engine for my next game since this problem doesn't exist in the engine I'm currently trying to move to.
