Thanks for the feedback! I'm glad you enjoyed the game overall. I'll add some sort of icon for aiming the fireballs, that'll be pretty useful for the player. There is a level select for the game, you are supposed to have 30 seconds in order to fight the boss. I forgot to add a check while the player is normally advancing through the levels so you got in with only 24 seconds. I'll also experiment with keeping the mouse inside the window. Thanks for the great feedback!
