@frankster -- Amazing. Thanks so much for getting into it and giving us all that super helpful feedback! It definitely made my day yesterday (and today) to know you're enjoying the game.
I've thought a bit about how asteroids crashing into ships (and possibly other asteroids) could cause damage. I think it's an awesome idea. We'll probably play around with adding that in and see how it feels.
We've gone over powerups a bunch in the past couple years and we always come back to keeping them out, since it would take the game in an incredibly different direction. With powerups, it feels less like it's up to each players skill where everything is more balanced, to how well you can collect and use those powerups. That said, maybe it'll end up in the 3rd version of Astervoid (if we end up making something like that someday) :)
Cheers, thanks again!
