v2 of DropSum. Completely re-written from the ground up (I've learned how to program a bit more since the original!) and with new features...
Using the arrow keys rotate the game board to re-arrange the tiles - very useful for getting out of sticky situations and for advanced players.
Clear 10 tiles in one go and you'll earn the power-tile - hold the mouse button to charge the tile before releasing it to slam into the pack.
