Suggestions:
Create a scoreboard for during the event displaying the top miners, what their block count is, and what your personal block count is.
Add an armor set, sword, and axe to the crate.
Increase the number of cores and frags rewarded from the crate. I'd say 3 cores, 20 frags.
Create a scoreboard thing for top ManaSweeper wins. Not monthly. No rewards. Just for interest.
Change the 15k mana crystal from crate to at least 50k so it's actually somewhat rewarding for winning. (ref. pond generally gives 1-3 30k crystals a pond)
Increase the money reward from crate to at least $10m.
Change the name to SSMSweeper.
Add an SSM NPC.
My thoughts:
The ore blocks kinda suck. Slow falling from coal is more of a negative effect because you're bound to have mining fatigue already making it super hard to mine anything. Maybe it can be changed to jump boost 3 or something?
I think the message announcing the event in the chat is kinda spammy. Especially the count down from 5. I think the messages minutes away that are large are good, but if the closer ones, 10s 5 4 3 2 1, should be changed to something like when a normal mine resets "ManaSweeper will be starting in 5s" as the whole message.
Excluding the timing error of the event today on Atlas, I am very pleased to see this is bug free (for now lmao). So thank you Sunset, Rory, and all the others who have helped plan, construct, execute, and operate this addition to hungry Olympus.
