Restart, Enemy-Types, and HurtBoxes - Version 0.2.1

Pushed out a quick update to make it feel more like an actual game. Here is a small changelog of some of what I did.

• Slimmed up the Player's HurtBox to make it feel better to play.
• Adjusted enemy graphics to better fit their types.
  • Gave the heavy-type the ability to fire at the player.
• Added particles for both when the player hits a target, and the enemies' projectile trail.
• Added the ability to restart the game by pressing the <R> key.
• Adjusted score for bullets on hit from 1 -> 3
  • Adjusted the heavy-type destruction score from 20 -> 4

Quickfix 0.2.1b:

• HTML5 doesn't emit particles properly, so I made few adjustments.
• Also had to make it so the score reset after you press <R> as well, since it wasn't.

What's planned for the future?

• Lives system, so players can get more than one chance to get a highscore.
• Power-ups, to adjust how the player plays the game.
• Refactoring the spawning system to be in waves and not random.
• More enemies, because 3 is just not enough!
• Title and GameOver screen.
• Local highscore saving.

As always if there is anything odd or amiss, let me know! Or if you have suggestions I'm willing to listen and maybe make changes!
