Hex3 [free arcade game]

Hello everybody,

I would love to get some feedback for my latest game.

play.google.com/apps/publish/?dev_acc=15109464606657860031#MarketListingPlace:p=de.denniswittich.hex3

It's called Hex3 and it is basically a hexagonal match 3 game (That's why i choose that name ).
I doubt that anyone doesn't know what match 3 means, but in case im wrong:
Match 3 means you have to line up 3 blocks of the same type (same color in my case) to remove them.
Right now the game includes 19 treasures (unlockables) in three categories:
Upgrades: Unlocks special combinations of blocks that remove more blocks if you create them in game.
Mods: Modifications of the behaviour / background of the game.
Mini Games: Three very simple minigames.

Here is a screenshot of the game:
