I've now finished up work on level 15 in High Fives, as well as added more achievements and leaderboards to the game.
Previously, I had only a single "overall" leaderboard that tracked the highest score earned across all levels, but I decided that players might also be interested in seeing who has done the best on a per-level basis. With that in mind, every new level now has its own leaderboard so that players can compete for top score in each level, as well as compete for top overall score.
I'm still trying to come up with more ideas for achievements. Right now there are seven achievements in the game, and I'd like to get that number to ten for release. I already have an idea for achievement number eight, but I need to come up with two more... hmmm.
