Drop Block Version 1.3 Released

Here is the change log:

• Adjacent blocks of the same color are now considered part of a match after 3 vertical or 3 horizontal blocks have a match.

• New double-score mode: after 4 or more blocks have been cleared, the game enters double score mode for 10 seconds and 5 additional seconds for each additional block.

• Invincible block added: each level complete will generate an invincible block (or more based on level) from the current blocks on the game field.

• Various visual and performance enhancements.
