I love it <3

Cool concept!  I like the idea of switching between two characters to co-op with yourself to stay alive!  The lighting looks really good and you managed to make a flat 2d game have plenty of depth.  A few comments:

• A cooldown timer on the weapons
• Animations for the sword/staff
• More effects/particles on enemy death
• Maybe item drops/hearts when killing enemies

Overall it seems like you achieved a lot in the 48h to make this.  I think another few hours of polishing and you'd have a great little survival game.  Really good job!
