score - imposible 31.
For a first using flixel this is okay.
I like that you can jump straight into the game or restart quickly. Having a level difficulty is a nice touch.
On easy, the sense of space is open, & there is enough time to avoid obstacles in either direction. I think the difficulty should reach a cap when the player cannot dodge the moment the obstacle is visible.
I think a 'prediction' game mechanic could be more fair. Allowing the user opportunity to make narrowed predictions to save themself.
- limited spawn positions for identifiable danger zones.
- spawn groups for familiar maneuver types (e.g. alternating, targeted, or clustered formation of obstacles).
- pattern sequence for predicting the next group to avoid (i.e. a wave may have a sequence of 5 spawn groups with the first being the same but the last being random).
Simplicity is key.
