Recommend a game for a fan of Aaaaaaah!
...mass=forceXacceleration...at least it's named something like that. I'm not looking for a Falling Fred or a Boost; I'm looking for a high score chasing game that captures some of the speed and character of Aaahhh. Not a bullet hell game though. If you've played it, you'll understand, it has a lot of character. And if you haven't played it, then make it the next game you buy!
