revert ended game

[zz-ha-dum]

Have you died? then continue playing the next level only to have annihilated every wave? But oh noes you're dead?

retore game, earn back lives, or play with undead powers like necromancy

[mjaun]

I don't fully understand what you are saying. You would like to be able to continue playing (infinite lives) after the game ended?

[Bretos]

Yes, exactly! But only count score until you run out of lives.

It would also be a great feature if every 5 or 10 waves (or 10k, 100k points) player earned one live.

Here one idea - if you completely kill 5 or 10 waves then you lives could be fully restored - 20 lives.
For example, if you missed few enemies from waves 10-20, and if you fixed it and killed all enemies after that... Then your lives will be fully restored before waves 40-50.
