Thanks for both of your comments! The whole boss fight definitely needs a overhaul, it was actually made in the last two days of the jam if I'm not mistaken. For the controls distinction, they were displayed on the HUD under the health bar and in the menu as well - but I understand D-Pad and Right Joystick Button was counter-intuitive. Simply, the complete game will have 5 characters, and Zyke will stand out so it's not on the D-Pad. It's not as noticeable on keyboard; it was keys 1-3. Also, it's noted for the puzzles, thanks for your feedback!
