Really a nice time waster, relaxing and feels well made, solid.
Through my progress isn't saved. Is it just me? Could it have something to do with connection because I can't seem to unlock the Opulent medal even if I have mastered more than 3 levels (I have now restarted from zero three times and re-mastered +3 levels each time).
Also how can one get the "Pent-up" medal? Make a pentuple (5 rows?), when the pieces have 4 blocks? Or are there bigger shapes later? Just asking because nobody has unlocked that medal.
Edit: Thanks for replying. I switched browser from Opera to Chrome and finally managed to save my progress!
...and this also unlock the Opulent medal. :)
Edit 2: Bad news: Since my above comment written yesterday, all my progresses have disappeared again! I had played the tutorial on several browsers (Opera, Chrome, Firefox & Edge) for testing purposes and now, the next day, they are all reset to zero. So I'll give up advancing, but I'm a bit weary of constantly having to re-play the tutorial, is there anyway to skip it?
