Wow, this is really, really cool. Runs at 13 FPS on my laptop, but whatever. Bravo!

The save slots are actually using playerprefs - I plan on putting the game in a few places, so I don't really want too much to depend on kongregates API. It writes out a string that looks something like 0>1>3>0|11>04> etc. and when you load, reads it back in using > to mark the end of a number and | to mark the end of a section. I can post the code on the unity forums if you like, but it isn't particularly well written :/

Thanks for all the comments/bug reports. Kongregate has easily been the most useful place I've posted this :).

impet: Thanks for letting me know, I'll try to figure out whats going on.

CarbonTech: Yeah, there is a bit too much hitting new players at once right now. Eventually, I plan on having a level up system, so you'll start out with a ship that only has basic movement and a single primary weapon. That will make the game easier to learn as well as providing some motivation to keep playing.

The scoring system gives points for time survived and enemies killed. To get loads of points, however, you need to keep a high multiplier. The multiplier is increased by killing enemies (particularly big ones), and drops down over time slowly. Your multiplier goes right down to 1x if you get hit, so the big scores come as much from dodging well as blowing stuff up. One trick that works well is to drop a heavy bomb then turn on your shield - the bomb will kill lots of enemies, and the shield will stop it killing you or resetting your multiplier.

Very nice game, at least to the point I've gotten! Which is only to the point in the tutorial where it asks me to use tab to switch to mines. No matter how often or long I press tab, I still have missiles as my secondary weapon. I finally just kept right clicking while holding down tab, and in addition to firing off many missiles a mine finally launched and it let the tutorial continue.
