I wish there were more power up bonuses

I get stuck on a level sometimes and the occasional bomb helps, I just wish there were more options for power ups.

I only played the demo but I just kept sending tiles where there were 2 of the same colour into the board randomly because then a bomb would appear sooner or later - I got the impression one would be created every x number of tiles - so by mindlessly making matches I could guarantee a bomb would appear.

That's not going to solve your "wish" but it might help a little.
