Extremely great and addictive game, although simple, the music was awesome and the whole atmosphere change was tons of fun. A friend and I were playing and already developing strats and exploits (moving diagonally gives extra momentum which lets you outrun demons quicker, this is likely due to adding the velocities together when two directions are pressed). 

Lots of fun! Thanks for entering and good job!

I liked the controls and the initial world with the grass.
Not sure what the relevance to the theme is and the demon levels were very unforgiving, but that's reasonable given the time.
