Really? I bet this without wallkick. Just stand bellow that vertical corridor and throw the hook straight up. Then move left and the hook will grab the small crack in the wall.
Nice game, but getting the last badge is veeeeeery boring for two motives:
1 - The auto-saving. What if I was doing fine until day 14 and then I did a bad fly? I would just want to replay that day, not waste all my effort.
2 - No "back to the main menu" button. You have to reload the page and then clear your save data to play again.
