I recently started to play it and I must say i love it. I never played any music/rythm games, but that looked interesting so i tired it and I don't regret.
I post it here because I see how this game could interest some of tetris players (I believe few people here already play it).
Yes, it is just clone of similiar game from DS, but big community and almost unlimited number of songs to play make it very unique expieriance.
Some things i learned already (could be good tips for beginner):
-avoid very old maps, often they are unfairly hard only because of their bad design
-instead of clicking with mouse use z/x keys
If you want, post your in-game name (my own:
Wojtek) or/and maps you recommend.
