Thanks for your feedback, maybe you had enough time to make proper main menu & pause options but this is life with game jams.
So yes, it's a first prototype it's not supposed to be perfect, same with other 90% games in this jam, we play keeping in mind they were created in such short time.
Note: focusing on positive points rather than bugs (that are very normal) would help people do the same with your game... however thanks again, rated.
