Updated Demo

Thanks to some feedback, there were some general updates to the game and demo.

Bug fixes include: 

Killing minor mobs during cutscene

Lunch boxes should be useable when acquired

Certain items shouldn't be duplicated

Fixed fps problem during boss

Mob health had been slightly reduced to fit combat flow

Collision system had been updated so that you can slide across objects smoother

Feedback was much appreciated. Thank you for playing the demo.
