Very nice work!! But what′s missing in this game is that the optimization is not good enough I think.
Could you add some checkpoints to the gauntlet mode?
It would be nice to add more actions and attacks to the city leveling mode. It′s boring to squash everything just by walking around.
And I have an idea for a new mode--Protect. In this mode, you are a giantess. But your goal is not to destroy the city, but to together with the tiny′s army to protect the city and tinies under the attack of something else. Move carefully, your inadvertent action may also cause a disaster to the city, citizens and your teammates. （Maybe you can also play as a member of the army and protect the city with the giantess?)
ps. I hope you can understand my poor English. :)
