Thank you Aaron ! I really wanted a contrasty 2D/3D aspect from the begining, i'm happy you liked it :)
As for the 3D aspect of the game, i guess it's thanks to the team having definied roles (The lead was the coder, etc) and i was almost fully commited to the 3D modeling & Level design of it (appart from i'll say 10% of 2D/3D shader work & team helping)
The first level is pretty straight forward, you simply get some dust, and give it to the Vacuum to Overload it 😊
