I'm aware that it is a design choice, not a bug. However, it is an accessibility issue for some people. For example, it's painful for me - I'm autistic and hypersensitive to some visual stimuli - and it's also potentially dangerous for people with photosensitive epilepsy, as there were no warnings about flashing lights being present anywhere on the game or its description. I hope this helps to clarify things!
If you choose to add a means of disabling the flashing lights, please let me know and I'd be happy to update my review accordingly.
