has an application called Graal players worlds that has the delteria, and I play it by this application, myself and others, I want to know if our accounts will be reset when the game launches, well hope not, we work hard to get things  

Hi there! You should identify and verify your account via emails, just click menu and identify yourself, once you already do it check your emails and click the link by the given of graalonline classic  

not what I'm talking about, I want to know if the accounts will be zeroed just like they did with the old players in the delteria  

Yes, beta progress will be cleared upon release. That said, there are plenty of reasons to still play.

There's a founders pack up for grabs - you can earn it by reporting bugs (if you earn it, you'll receive it once the game releases). It consists of: 500 Gems, one head upload token, one body upload token, a month of VIP, and a hat exclusive to beta testers. You'll also keep your knowledge of the game, which I'm sure will come in handy upon release.  

I see a lot of bugs, so I'll report them, will I get this package when I release?  

Maybe, I'm not staff on Delteria so I can't say for sure.

I would recommend checking out the Delteria Beta Discord server / Trello when reporting bugs to confirm the bugs you see haven't already been reported. If you would like an invite link, message me on the forums by clicking here and I can get one for you.
