Hi :)
I just released a new version of the game (v3.1) that fix a lot of small (and bigger) bugs.

• The most important change is on the way the block moves, as they now try to reach your mouse position at all time.
• Some levels that were really to long has been simplified (mainly on advanced levels)
• Some levels that were not playable due to a bug are no playable again

I tried to test this version way more intensively that the previous one but if you still find a bug let me know.

This 3.1 version is the last one before a big, big update (allegedly bigger than the 2.0->3.0 update)
