Thanks for trying my game and the feedback! I love your idea of a cone for the enemy's detection field. I would definitely make the game feel fairer and would help avoid having enemies detect the player through walls and such. I also like your ideas for new abilities. On the 2nd to last day of the jam I started working on an ability where the player could spawn a "dummy ghost" for the enemies to chase and lead away from the player. I wasn't able to complete it in time, but I think an extra ability would definitely spice up the gameplay. Thanks again!
