Love the game; maybe more options?

I love this game and have played it ever since I had my first 2nd gen touch. I just wanted to say I think I cool option could be maybe the chance to repeat a wave instead of repeating the full round again. Like an "undo" button. Id even pay extra for that option haha. Game is very addicting though. Hopefully Ill collect all my stars one day. But some levels are quite difficult to even finish!
