It's ridiculous.
As much as I loved this game when playing on casual mode, as much as I hate it on normal. It's called NORMAL mde, not frigging hard you-can't-get-higher-than-day-13-without-the-hunter-and-awesome-luck!
5/5 on casual, 2/5 on normal mode.
Man, too easy.
Just start the game, and wait until there is like... a lot of ennemies on the screen. Then shoot.
It gave me 3153871 points, 876441 HP and 691 combo.
There I go, I got all the 1010 coins!
Great game, 5/5, hard like I love them :)
On the 7319 death I had, over 2000 went only for the level 40! I was getting crazy! :P
