If I didn't know this is in a jam I would have thought that this game was made in the 90s, so to be clear the game is nice and all but, it was just a straight of copy from space invaders with less stuff to do I like that the rate of the game increases over levels but, that's not enough the enemies move in the same direction every single time so it's so easy to predict there next move the bosses hitbox is really small and just makes no sense the game didn't fit the jam theme that well too the sounds are alright the UI is good and the artstyle too overall I would give it 5/10 if you had worked on the gameplay and enemies more I would have rated it better but, anyways well done :D
