Really liked your game. The idea of flipping between top and bottom adds a lot of depth to the game. Also the idea of adding obstacles each loop is a great way to ramp up the level along with the player skill level. Also by only having the player go back one loop it lets the game be difficult, and have a punishment for dying without being rage inducing . It actually lead me to plan out optimal routs while I was playing something I had never done in this genre. only gripe I would have that it is jarring that the obstacles only spawn in after you make a full loop not just when you pass them because sometimes when you went past the start the would spawn into your way.
