i never got around to playing it, but looking at the gameplay, it looked like such a fun, lively, and polished game - and i have a real knack for virtual worlds like it. the trampoline at the center of the main room in particular caught my eyes even years after, genius! wish i could've played it. instead i just watched all the let's players blabber about it back then.
i did remember it being very blatantly freemium, with many minigames restricted unless you had some sort of membership, not a good look at all. it was also quite crowded with disney ips, which sounds fun but can come off as annoying for more veteran players of club penguin.
the reception was understandable - they could've retrofitted the main game even without flash, but instead wanted to make something different to overwrite what monetary control they had of the game, and people caught on to that. may an mmo never fall victim to the hands of disney again.
