More levels

More levels please. Game is great but 100 levels went quick because this game is addicting.

I dont like that we cant switch or add upgrades once the 100 levels are completed...spent a decent amount on those upgrades.
Maybe add an expansion pack or at least allow for levels to be beaten a second time without losing upgrades.

--or-- allow upgrads to Cary over to next game...thanks...the game itself is fun...good job
