I'll tell you that I found this game by searching for 3D games tagged with Flying, and I'm so glad I did!
This is an absolutely fantastic demo. I love the retro-ps1, y2k look that this game goes for. You can feel strong influences from Spyro, Jet Grind Radio, Mario 64, and Sonic Adventure. I absolutely love how it all comes together. The tutorial is excellent, the controls are incredibly intuitive after playing through the level.
I love when the big enemy chases you, it becomes so easy to slip up on the controls just from the panic of it being right behind you!
