Would be nice to be able to save/retry waves, or at least add a few checkpoints during mission. Difficulty comes not from proper planning, but from trail-and-error, one bad airstrike and there goes your half of your defences. I'm so tired of grinding through the begining waves knowing that split second timing on the last wave is what would give you that perfect victory.
