Fun game...glitch somewhere... – Clever Block Puzzle King Review

I tried to buy more hints the other day and it didn't work... So stupidly, I tried again...didn't work. However, I was billed twice. Fix the problem or I delete the game. It's a fun puzzle game... Which is actually hard to find. For the most part, I like it, however: 1) I bought the 30 hints for $0.99 (which is a decent amount of hints, thank you to the developers), but I can't tell if I've actually received the 'extra' hints earned on some of the levels. 2) The earlier levels that are much, much larger puzzles are nearly impossible to finish within the three-star time limit. I wish the time limits were extended just a little... Even the puzzles became something we could finish with one-star, tat's better than level after level with no stars.
