Powerups!

In this update, the biggest new feature is the power ups.

A little bit into the game Power ups start to show up. Currently, there's only one power up, which boosts the firepower of the Player.

The player and enemy sprites are a little bit smaller than their previous size.

The game playability was not so good, as I was working mainly on technical features of the game. After talking to some players, I thought that I should not take the fun out of the game. So, I hope the current difficulty is a little bit more entertaining.

Please drop a line or two, to let me know how the game can be improved.
