Castle Doombad. Long missing are the days of PvZ (the first one, dont even mention the "sequel"...) where IAP, double currency or heavy grinding didnt even exist. In Castle Doombad I had to re-re-replay the entire first and second world (some stages even more) (you get less money each time you replay a level and that doesn't help) to buy some upgrades, but I haven't even upgraded everything yet and there are still things to buy. Grinding by replaying and replaying levels (or IAP) to get crowns removed some stars from my rating (of my idea of fun is) but some endless action (one game where I lasted 8 nights), and the fact that the game is well done and joyful to play helped it get my vote.
You don't get less money each time you replay a level ( I've replayed 1-12, 1-13 and 2-12, 2-13 over and over, always getting the same amount of coins after I completed them) You get half the money if you loose the princess (don't get a crown)
I have to correct that also, I was under the wrong impression. You get more coins the further you get into the world (that is what happens when I replayed the first levels of each world instead of playing the world from beginning to end), so in the first levels you get 100 and on the last one 1000. Good. Almost finished all levels with all crowns, 2 levels left, review following soon (hint: its gets a big score).
