Maybe you should have a look at Voodoo. it's a (hyper)casual games studio. They have an academy program. I haven't tried it but it has been well presented to me. Source: over 1 year ago

Hello. I have contacted Voodoo (voodoo.io) with my game. Their site stated that they review all the games within 48 hours. Those 48 hours have already passed so I decided to ask them personally using email but I couldnt find their contact email anywhere. Does someone know who am I supposed to ask about this or know their email? Source: almost 2 years ago

Or even CSS media queries. Although I understand that diep.io is built on C++ (from another post), it's still compiled to Javascript on the client side. I don't use C++ that much, but there's definitely a method to get around this, in addition to that most people who play diep.io play it in the app, not the web. Source: 6 months ago

No updates , downfall started 6 years ago , barely any diep.io content creators still there , it explains it self , diep takes more skill than arras.io , meanwhile arras.io got a ton more classes and more fun , and bullet logic is different there , don't forgot arras.io gamemodes too .
