Last update:

Final version of the game released.
I managed to put in some animated sprites and music. A shop and  a boss fight also made its way in somehow. 
It's a shame about the sprites for the generic enemies and item pickups though. I couldn't change them because making new sprites is too boring and time consuming.

And about that really old copyrighted music at the end when you beat the game... Never mind, I'll leave it at that.
In the end, it's just for a joke. I'll change it if necessary though.
