Thanks Kiji, this was a very useful write-up. Here's each part.

Fixed and LIVE now:
- The Moon Bunny floating in the moon. Its spawn point is the moon itself, and in the original it drops down onto the first platform underneath. Ours skipped that step. It now lands on the platform.
- The pigs. Those were the Pig Town bonus-stage pigs, spawned by mistake. The original has no extra wave when the flowers bloom; the attackers are the map's own Flyeyes, Stirges and Goblin Fires. The pigs are gone.
- No rice cakes. The original bunny makes a rice cake every 20 seconds while it's alive, with the message "The Moon Bunny made rice cake number N." Ours only paid a cake for killing the pigs, so you got none. The bunny now drops them on its timer. Growlie keeps the 10 cakes when you turn them in.
- Tommy sending you to Kerning City. After a Return Scroll he'd lost track of which party quest he belonged to, and defaulted to Kerning. He now takes you to Henesys Park, as in the original. He also now offers the Pig Town bonus stage after a clear, which wasn't reachable before.

Still open: planting isn't shared across the party. Each player plants their own seeds, sees their own bunny and gets their own cakes, when the whole party should share one moon and one bunny. That needs the party's progress kept in sync through the game server, and it's with the person working on that server now. They'll reply here when it's live. For now this runs fine solo, or with each player planting all six seeds.

Quick update on the one part still open: getting the whole party onto the same moon (shared seeds, one Moon Bunny and shared rice cakes). The groundwork is now live: the game server keeps track of which party is running a party quest, even through a restart. The shared planting, bunny and rice cakes are being built on top of that next. We'll post here the moment it's in.

The shared party version of Henesys PQ is live now. When your party plants the seeds, everyone in the party sees the same flowers bloom, the same single Moon Bunny appears, and the rice cakes it makes are shared: one set for the whole party. When the leader hands Growlie the 10 rice cakes, the whole party is taken to the next stage together, Tommy's bonus stage takes the whole team, and if the run ends early everyone is sent out together. If the party drops below 3 players or the leader leaves, the run ends for everyone, just like the original. Refresh the game once to get the update. Kiji, could you and your party give it a try and reply here with anything that looks off? A few extra touches from the original (seeds that must be dropped on the flower spot, monsters that can hurt the bunny, and the 10-minute timer) are still to come.
