I can also add a few things from my limited experience with it:1. Bullets you touch with your shikigami, that you have not already turned into gold, will flash pink+blue. They will turn into gold once you destroy an enemy with your shiki.
2. You can "coin stream" with your shot anytime just as long as your skull counter is in the gold area (not sure about this)
3. You can't really milk bosses with (A+C), but you can destroy a boss's objects and turn bullets into gold. ex: the pods on the back of the stage 3's boss or it's tiny spiders. You can milk with A+C but you won't get as many coins.
4. some boss's attack are much harder. [stage 4 boss (last attack), stage 5 boss, stage 6 boss, and TLB]
5. the monkey boss in stage 5 grows as you're shooting. i.e. making it really easy to defeat with your shiki.
6. When you bomb, any bullets your bomb touches will turn into gold.
- Flashing enemy bullets move slower for the rest of their duration, as opposed to normal Guwange where bullets that you slow down become faster than they were originally once you stop slowing them.
- The chain increase you get from certain coins might be different? I can get to 1000 coins much faster than in the normal version.
- It seems safer (for your chain) to bomb during bosses; the skull meter seems to stop draining (or just slows down dramatically?) once it hits 2 skulls.
