Not a bad concept. Actually kinda similar to our game in the fun 3D perspective idea.
Which makes happy, good to see others trying that idea too.
If you took this idea and polished it more, with enemy variety, I think it'd be pretty epic. And maybe more momentum/flow to the rotating movement, and that'd be the cherry ontop.
Great job mate. (Also what was the intro about, seems detached from the game)
