I couldn't find any warning regarding this in the forum or on the game page itself so I just wanted to put out there for other people: there are major flashing lights/colors right at the beginning of the game. I couldn't figure out how to navigate the menu, so maybe I did something wrong to trigger it, but I had to force quit immediately. It's way more intense than what the preview images display.
Absolutely no ill will or anger towards the dev(s)/mod/anyone else; I just want to look out for any other people with similar sensitivities and issues who check the forum/comments! :)
