Quoted from Damien:
How do the extra balls in 1.80 compare to previous code?
Easier. Combos are 10 instead of 20
Blown pistons increased to 15, but they work right now, so you can get up to 3 at a time.
Coffin hits are 10 for the first and 30 for everyone after that. Before it was auto adjusting, then 100 for the second one.
