Yep, thanks! The USB thing of my controller was connected and, while the controller was turned off, disconnecting it made it work.
I beat the game (after 3 or 4 tries).
I had a lot of fun playing the game. It looks great, overall it sounds good if arguably sometimes a bit silent and I thought the hammer was a delight to control, it make you feel strong when you manage to make it turn around you to destroy all the bullets nearby and if possible smash the enemies as well, I got rid of the last phase of the boss before the arrows very fast during my successful run. The difficulty is perfect for the jam, it was satisfying to beat the game.
Thanks for sharing!
