Submitted first then saw the requirement. Decided to disclose that this game is indeed not 64x64. Decided to keep it submitted as it was made for this jam as usually jams have not only successful projects (look at ld or 7drl some projects fail but yet they still are submitted as they were made for the jam). Did not expect that it would cause frustration in other people.
Edit even though I did not in the end meet the requirement I did something while often many people dont. So showing not only successes but also failures can encourage more participants to actually finish and share their projects because thats what the jams are all about.
