I hate this game(In a good way don't get me wrong) I feel like I spent an eternity playing this game(3-4 hours).
The game feels like it's a full game already. Well done.
I guess, I have cleared every level available since I don't know where to go next. I just follow it through the first level and not stop.
But on the last level, I never managed to get the picture right (I spent an hour alone on this level) until I re-opened the game and it worked somehow.
There seems to be a little bug when pulling the frame too fast player can get outside of the frame without dying.
Nice.
