You have no idea how happy I was to see this here! As a young lad, I was a huge fan of these lcd games and find myself time to time play these. There is a very nice archive (https://archive.org/details/handheldhistory) and another website (http://pica-pic.com/) to bring you all the nostalgic goodness and some inspiration for the future. Great job on this! Not sure if you know but these lcd games are making a comeback.
Thank you so much for submitting this gem to our game jam. I will be putting up a higher score! We hope to see you submit to our future game jams :)
