Yes, the new Castlween map is good, but not the best. The music is a bit strange, it could be better. I miss the 2 trapdoors (where orange lava light lighting on the castle) could open after a time, or if we run, jump on them aciddentally, or with purpose and we could fall in there, when i break, or open it. In there could be small room with lightning pumpkins with other few Halloween decorations and/or with a place with lava and if we fall into it, we die/knocked out. :-) But there down on the wall could be a broken ladder, which have 50% chance it's totally break, if we try to climb up to be saved and 50% chance is not break and we could climb up successfully. If we stay down there too much, we could die after 1 minute, because there too warm/hot the temperature. But i don't think developers will add this feature for the Castleween map/level, because it's too late and maybe a bit too difficult to make it in hurry for 1 week event. Maybe for the next year's Halloween event.
My favorite maps/levels: Lollipop Factory, Blackhole Lab, Buzz Ball. I have more favorites too, but this is my top 3.
