• - The game no longer crashes when trying to access the leaderboards
  
• - Improved the leaderboards ergonomy to avoid displaying all entries at once. There is now a page system, which displays up to 15 entries.
  
• - Added some optimizations on leaderboard, which should prevent any freeze to happen
  
• - Finishing a level should now unlock it permanently in the level selection screen
  

We are aware of the performance issues you might encounter, especially in the disctrict 2, however performance improvements are very unlikely to happen since it would require a lot of additional work, and probably a full pass on all the levels, which is not feasible for us right now.
