Thanks for playing!
This is my first time entering a jam with resolutions and colors restrictions, many things just flew pass me.
When i built the game with the resolution of 640 X 576, I also decided to re-export all my assets at 400%. Now that i think about it, i really should not have done that. Just realized doing so had ruined a Gameboy themed 160 X 144 guideline.
And I totally forgot that anti-aliasing existed, should have turned it off for sure!
Thank you very much for point out all the issues for me! :D Definitely will help in futures jams!
