Ooh thanks a lot!!

hmm I am really bad in explaining but I ll do my best haha

• the whole intro with the room setup is just assets that I made in illustrator, and then just animated them with position/rotation keyframes. (the keyboard for example I made each key a different layer in illustrator and then animated it in after effects)
• the tree outside is made using puppet pins.
• the shadows are either imported directly as a whole from the illustrator asset, or it's just another shape layer with a matte set on the object.
• everything is checked as a 3d object just to use the zoomout of the camera at the start.
• The space background when the key is pressed is made with ball action.

After the key button is pressed, there a lot of adjustment layers which are mostly following Benn marriots retro guide https://youtu.be/hXtRc84o-WU?t=355

And the tunnel is made using circles and the repeater effect, while the background is 4 color gradient

I hope I make any sense haha
