I think for the length of a fireworks game and the new payout, I could have had a couple of CTF's and won more credits. I may try it again when i get to my own computer as i'm on my brother at the moment.
I would say it's a good change credit-wise since you get credits even if it is miniscule. Though scoring high may be a problem initially but it gives a better chance for everyone to get higher scores.
The game is what it should have been when it started. Random not the same patterns everytime. I score in the 200k range in old fireworks, but I welcome a random and new challenge.
I'm not really sure yet. I only got to play it three times and all three I stayed in 6th place, thus never making it to the final round. The Frontierland stage was brutal to me. I'll have to play a bit more to see if it really is possible to actually get GOOD at the game or if it's just hit or miss, then I'll have a real opinion about it.
