I have test 2 game at the moment i wrote this topic. If i'm not wrong this game jam is dedicated for Gdevelop . Then why i see 2 games in 2 i've been tested as made with pixiJs ?
If you submit a game using GDevelop, itch will automatically apply the PixiJS tag to the game, and you have to then manually add GDevelop to your game's metadata.
We can check the game files to know whether it was made with GDevelop or not, so no worries there. Only a game made with GDevelop will win the jam. 馃憤
