You mention you wanted to create a N64 feel and damn you nailed it! It reminded me of Glover and Rocket: Robot On Wheels! I loved your prototype <3 Can’t wait to see it completed!!! Camera sensibility was too high for me, and I believe an outline on platform’s vertex (or more / different lighting) would help distinguish between platforms. But I was so surprised and excited to see a mario-sunshine-ish jetpack when you press jump twice!
And of course, well done for cutscenes to hint what’s next. Music, sounds, goofiness, dialogue, style, cutscenes, tutorial, to the logo being a N64 jacket, you killed it <3
