Wrapping up
I hope I didn't miss anything here, if you have any doubts or something, please let me know.
Again thanks to Kyatric for the plugin and Galactic Octopus for the example *.capx.
I used r143 to modify the .capx, so remember to install the plugin also, otherwise, it won't open.
You can play Derez on Game Jolt to see the achievements and leaderboards implemented :D
Thanks!
Luke
