Onboarding: I miss reading about the background story. I read the objective of the demo game, but why are the ships there?
Tutorial: Great tutorial! Perhaps with a keyboard overview where the keys are seldom used?
Initial play: Nice to see my ship flying around, but I didn't catch first buoy :) It seems a bit complicated to play, and using too many keys on keyboard is a little minus for me. Would be nice to use mouse, left-click, right-click as functions in the game. But 3D games is not my cup of tea, so I'm sure it is great for 3D gamers!
