The game could use some controlling improvements.
The idea of a crazy grandma protecting her cookies is a fun idea and worthy of taking another look into.
The timing for combos works.
But Grandma could do a 'spin-attack' by holding down while pressing "A" or "SPACE".
This way, she can get from one side of the stage to the next easily. Allowing for more timing and strategy for defeating the final boss and earning higher points from bonus stages.
However, the spin-attack needs to recharge.
But for a game made in 72 hours. It's not BAD!
