Anyone know if the DLCs add more music? Or how about the fish in the fish tank?

I have the original ANIME TETRIS and SPACE HENTAI TETRIS Dlc. It is good to know that there are only 2 colors to play blue and red. ;D. ACHIEVEMENT 1 HOUR is NOT unlocked, game 1 hour in the Dlc?. Does it work achievement 1 hour?

-The blue and red barriers on the left I have no idea how they work. -Green and red lights on the right with a number. -I played the usual tetris, making rows some stay in blue and others in green and break. -The first photo seems to have on its right the number 100 in yellow and some more numbers in green and red. - I think I managed to activate the first photo 100% without being clear about the color system. - I entered the gallery and there is beautiful landscape accompanied by music, but here ...

Wondering if this has any controller/gamepad support? I tried, but my gamepad doesn't work, only keyboard.

I purchased the DLCs and have played the game for a few hours in total and have ran into trouble receiving the achievement for two hours of gameplay (it's the only achievement that didn't work for me).
