Oh man! I miss the old eggwars so much! When I wasn't in high school yet, I lunched and immediately started playing Minecraft and opening Eggwars. Those are the memories, I miss it so badly :(. Also, constantly watching EnzoKnol (Dutch YouTuber with 2M+ subs) playing Eggwars and other games. Right, Dutch people? Those were the days...
About the suggestion though, yes and no.
Sandstone:
Yes, it made the game more intense since you could just sneak in and build yourself in and then destroy the egg. And it of course brings back much memories. Yes pls
No Emeralds:
Idk, it's pretty useless since only 1 in a 1000 (not literally) uses it. I don't care if this stays or not.
Old Villagers:
Again, I just want old Eggwars back. This system was a bit weird to use because ehh.. You had that moment where your inventory is full of leather boots? Me too. I support bringing old eggwars back, but the new shop is way better.
