Excellent, glad you liked it! The game restarts faster because it's loading fewer graphics in the background (the previous demo loaded a lot of images that didn't even get used or were partly off-screen. It's a good tip if you're looking to reduce load times even in your own game).
I'll make sure to keep the voice-acting in and add more to it!
The power-ups are dropped by enemy ships randomly and then the player has 5 seconds to upgrade the single laser, 3 to upgrade to rapid laser and 2 to get the scrap cannon. If you wait past that the power-up is gone forever. I mention this because this is one of the key things I'd like to know if it's a good idea or not. Trying to avoid having the player press a button to change weapons and I think this adds a little bit of strategy to the game (you can get better weapons if you're willing to wait and if you can get to them in time).
The player ship should be above the final ship, so I'll fix that for the next demo.
Thanks so much for the feedback!
