There's a new qrostar game. If it's anything like Hanano Puzzle and Jelly no Puzzle, it should be worth trying for fans of puzzle games.
You can get it

(pay-what-you-want, only for Windows)
Game rules are the same as in the first Hanano Puzzle (which supposedly is not required playing first). Move blocks left or right, or swap two adjacent blocks. Goal is to get all blocks to flowers. It's harder than it sounds.
Based on a look at the first few levels it seems that undo is now infinite, unlike in the first two games.
For reference here are the earlier discussion threads:
