Thanks for the feedback! We had a lot of back and forth on the bonus blocks so it works differently in the 2 modes. Initially we were planning to make it line up more like Tetris, so that may have also added to the confusion. It seems like the block placement should somehow affect gameplay... but not quite sure how to bring it in other than using it to sort by size maybe...
We definitely wanted to do a tutorial mode to introduce the mechanics better and a leaderboard and all that but you know how it goes!
