Notes:
The alternate application both hacks in 100 million premium currency at the start of the game and enables a debug mode.
The debug keys are:
T sets the amount of bubbles to an initial amount. (usually 30)
W sets the wild generation chance to 0
E loads a default (testing?) level in place of the current one.
R deletes the lowest row of bubbles
Y changes the puzzle to be symmetrical or not symmetrical. (I don't think this actually changes anything.)
U shows something about initial matches
I sets the fireball generation chance to 0
O sets the "Bad Bomb" generation chance to 0
S opens a dialog box allowing you to save a puzzle.
D says something about a "Initial Match Down" being 0
G sets the "Good Bomb" generation chance to 0
H sets the "Chameleon" generation chance to 0
K sets the "Initial Match No Fireball" generation chance to 0
L opens a dialog box letting you load a puzzle
Z restarts the level
C sets colors used in the puzzle to 2
B shrinks the puzzle by around one column for each press
N sets "Initial Match Next" to 0
M deletes one column of the puzzle, down to a minimum of 10 columns
Up Arrow Key moves the puzzle up one row
Down Arrow Key moves the puzzle down one row
Delete allows you to clear the puzzle while in editing mode (there is no known way to do that)
I was not able to successfully hack the 2017 build.
