Right here! :D
I've updated the game. Managed to fix a few of the bigger issues that were bugging me. Lots and lots of things have changed, so it's worth checking out again even if you've already played it! Here are a few of the bigger changes:
*
Online Highscores: There's an online highscore table available in the game, on alternativly
here!

*
Better Balancing: There's a much less steep difficulty curve now, with 25 increasing levels of difficulty instead of three. Also, the whole game is generally easier (and you now only need to beat 250 waves instead of 400).
*
New Enemies: There are two new enemies now, which should help mix up some of the patterns.
*
Graphical Fixes: I implemented the shrapnel particles from Annabelle's sprite sheet! Also fixed up the background a bit...
*
Low Shield Indicator: When you're low on shield power, you'll flash and an alarm will sound. A few people were telling me that there wasn't enough warning when you were in trouble, so hopefully that helps fix that.
*
Nukes: An extra powerup allows you to use nukes, which clears the screen when things get too hectic. Use them by pressing C.
*
Voice Narration: A robotic lady will tell you how many waves you have left to go :D
There are a few other things, but that's mostly it

Hopefully this version is more fun to play than the last one! Hope to see some of you on the highscore tables :D
(on that note, online highscores are a first for me, so please let me know if something doesn't work as it should
