Nice. I don't know if it pure luck or totally intented but congrats.

About the new event... it looks way more complicated than it is supposed to be. Not bad though. But it will be on the hard event side (It may be unbalanced since it's the first time but... I wonder if they will rebalance it on the easy side).
I somehow messed up with luck spirits. Actually, only the speed up spirits are worth it. I don't know why, I thought there was as much total spirits as fields (even if there is 10 spririts for only 15 fields...). Total waste of 1200 currency.
I guess the strategy here is buy the first 10 fields with spirits as soon as possible on phase 1 and then, save currency for buying the 5 other fields day one on phase 2. Then, throw all the currency in Speed boosts. I don't really know if leveling spirits is that worth it. I guess it is on the long term but there is too many fields/spirits to unlock before to make them worth it. Unless speed Boost only affect ONE field and not all of them at the same time (but let me guess, that's the case right?).
It's a kinda cool event but they should have done it on the last event. Doing it on Nihdogg when you already need to focus all you're time and stamina on phase 2 is not a good idea. Espacially if event phase 2 needs a lot of currency to boost the last fields. Last event was too easy and I overcompleted it from really far phase 1. It would have been with the giant centipede.

Speaking of Nidhogg, I always thought phase 2 takes place on Nidhogg body. If
that's the case, how it could be a giant lava maze here and a much smaller scaled body during Electric Moth event (when you fight on him). Or phase two take place elsewhere?
