It's a good game, a bit tricky at first but you get the hang of it pretty quickly.
Perhaps an indication of the flag's location would have been cool, or a zoom on the level at the start. Unless you want us to search for the flag? 

This is a really neat concept! The movement is challenging, but not frustrating well done :)

(there is just a bug that allows you to stuck your limb in the air, which make the game far easier haha)
