Hey, thanks for taking interest in my game! I did not expect anyone to actually play this, as this was the first Unity game I ever (kind of) finished! 😅
As for the ledge grabbing, that was definitely implemented, but the code was pretty terrible (the code was pretty terrible all round) so I am not surprised it didn't work as intended.
As I am pretty busy with other projects, I doubt I'll ever go back to polish this game up, but I'm eager to see what you come up with, I hope my game helped to inspire you!
