Port my web game to Unity3D using same NodeJS backend

About Players control a cell in a map representing a petri dish; the goal is to gain as much mass as possible by swallowing smaller cells without being swallowed by bigger ones. What I need. I currently require a mobile port of my game in Unity which will have good performance on mobile devices using my existing backend NodeJS server, so I can sync the servers from my web client and mobile client Requirements UI - Let me have my own splash/loading screen on unity (I only need it added there and can add my own logo there after etc so essentially a placeholder) - When the game loads I essentially want a screen like this [login to view URL] I want to be allowed to modify the background and and logo. (so in project files) I also want on the settings page that the user can modify background colour from either white to black and also turn off virus animations (You can see these settings in my web client) I want cells and viruses to be the same like [login to view URL] mobile app (Also server/backend is used to determine cell/player colour ) However i want it so players can pick the colour of food in game via settings. I want the in game UI to be essentially like this [login to view URL] 2 controls in the bottom right and the score and exit within the top left. I want a mobile joystick for the game for movement like the [login to view URL] app. I also want it so if a user uses a certain name they get a “skin” you can see this in [login to view URL] e.g if you name your player sirius Selecting Servers I want it so when a user goes on the homepage they click play and then they are presented with a list of gamemodes which they can select. Within the gamemodes they can then select a server to play on (Each server needs it so I can name them and also use country flags for regions) If you want to see what I mean please check this [login to view URL] Smoothness It is important that the client is smooth and in sync as it will be using the same backend as my web client I want to make sure users from mobile and web can play together without issue. Ads I also need Admob integration so when a user dies sometimes an ad is displayed before they can continue. Apps/Source I want the source of the project on completion so I can then publish it and upload my self to iOS and Android stores. GamePlay (Gameplay is determined via serverside) Eat blobs smaller than you to grow in size Use the space bar to send 50% of your mass flying at a blob to eat it Use the W key to eject some mass Viruses are the mid sized green 'spikey' blobs which cause blobs larger than them to explode into many smaller parts if they consume them (at about 150~ mass you can absorb a virus and explode) Small blobs (smaller than size 130~) can hide inside of viruses with no negative effects (use this to your advantage when starting out) Score is simply the largest mass you have had this current life. You must be 25% larger (mass) than another blob to absorb it (that means your diameter must be ~11% larger than another blob to absorb it) Holding down the space bar will cause you to cover much more distance when you split No longer true Feeding a virus, by using w to eject mass into it, 7 times will cause it to create another virus which will launch out of the current virus and go somewhere from 7 to 12 units in distance Helpful links This is my backend currently [login to view URL] Reference/Pics to get inspiration from [login to view URL] [login to view URL]
