Level 2 was tough! don't know if i died in level 3 or won it - I was a junior ghost in the end, so maybe not the finale ;-) very well put together and a nice variation of the flappy formula.
2 quick notes:
- it was virtually impossible to know which spikes were the really dangerous ones, because the color coding didn't seem to follow a specific logic - the flying enemies were easier to learn because of their distinct shape.
- if you want to create a parallax effect by moving the background at a different speed, it should move slower than the foreground, because of the rules of perspective. yours was moving faster and therefore disorienting.
