Hi, thanks for your feedback. I've thought about the Comeback-System but the only one I know are related to showing Ads. I think without Ads I'd to add another reward-system which the player could use to "buy" a comeback.
Well - the first option I don't like and for the second option I'd no time. Actually I wanted to have a Highscore as well (which would have become even more important with a comeback-system).
So you are probably right. That will give the player a reason to keep on playing that game. (But because I'm already in the next game-jam I won't be able to add all those stuff)
