aren't we allowed to make the game in any other engine(godot) plz

Unfortunately that is what the creators of this jam decided, so yeah, gamemaker is required.

This was probably done to make it more of an event for the gamemaker community over all.

Submissions for this jam have to be made in GM1.4 or GM2.2/2.3.

The jam idea came from some GM community members so that's why we have that restriction for this. Sorry!
