I’m not sure if the background moving faster than the obstacles was a deliberate design choice, but it can lead to dizziness/motion sickness for sure.
Personally for me this is kinda ignoring the theme, could have been an always moving bird, that turns around on walls, pressing one button changes the direction immediately, which be a nice fit.
Graphically and audio wise it was nice, maybe just a bit too loud.
The game idea was okay, kinda wish there was something ramping up (speed, number of obstacles, more difficult obstacles etc…) other than that, it is a nice entry.
