There should really be checkpoints between floors... I appreciated that they're trying something a lot more interesting than collecting spammy event drops, but goddamn lol.
I dunno, maybe we're complaining too early? I remember a lot of people complaining about MMF, but it turned out there were a lot of cheesy tricks you could do to fudge your way through it lol. Granted, each MMF level was only 2 mins, while these seem like they take longer per attempt...
Also, are the wondroids voiced? Are they the generic "You must be my boss! teehee" ones? If they have unique voices, I might need them...
They put it in a coin shop once, so maybe? I doubt they'd give it for just logging in one day though lol. Since Name Change Coupons are 15k NX. Maybe as an attendance reward would be a bit more reasonable? Like, the final reward in an event with very few spare days.
There's this thread from about half a year ago where they said they were working on an official MapleStory store. Would love an update on how that's going. If it's still going at all lol.
For stickers and phone cases, you can probably have those custom-made on some "design your own phone case/sticker" sites. I doubt you'll find very many premade phone cases for anything other than iPhones (if at all).
I usually use etsy whenever I want fanmade merch. I also remember buying some MapleStory stickers from redbubble. But I checked both those sites and their selection seems a lot smaller than when I bought stuff a few years ago lol. I could've sworn redbubble at least had stickers of all the major character classes (I bought Angelic Buster, of course). Was cheap, too.
