What if Angry Birds was released on NES? Well I have my answer now! I like how the physics work! Good job on that part.
I just tried the gdgames version and I have this issue of not being able to launch toward a low angle. However I was able to find a workaround by shooting at a very high angle with low power, allowing me to collects those eggs on the floor.
To emphasize the retro style I would recommend to use an 8bit song!😁😁😁
