Cannot complete game – Museum Of Thieves Review

First off, this game is fun and I played all three levels. But I can't seem to get the achievements for completing the game. My highest score 6112 is listed in the leaderboard, and I've played the game over for a couple of times, but nothing seemed to work. Please fix this issue, and I've enjoyed this game, thank you!
