This update is just more adjustments to the collisions when you use either a Smasher power-up, a Cannon Ball power-up, or a Spi-Roll attack against asteroids. Many complex formulas now try and determine the asteroid breaking and each pieces direction and speed.
The problem I had back before I started working on these collisions before update 1.23 is that too often when using one of those methods I mentioned above is that your speed was faster than all of the break-off chunks causing you to not even see the asteroid breaking up. As a result, this caused using the Spi-Roll attack, the Cannon Ball power up and the Smasher Power-up as well to be over-powered in a way as breaking asteroids using these methods was too rewarding point wise, and didn't present enough additional threat. (Remember my whole "Risk VS Reward" element being the most important aspect of my game from the very beginning of development)
After this update, I think it is now better than it was, but more adjustments to these collisions will likely be made in the near future.
I've heard that a good developer is just never happy with his game and these refinements go to show that might just be true. I'm starting to think that I'll never be 100% happy with the code and aspects of my game as it seems there's always something I want to adjust, balance, add, fix, or alter.
Hopefully this determination to make Rock 'N Roll better all the time will serve the people who play and experience my game well.
As always.. Rock On and Enjoy!
