Hello World! v0.5.1 is here

Hi there!

Fist week(almost) in Steam's early access and i'm already getting some useful feedback!

Thanks everyone who checked the game out, specially This Guy for
giving me some feedback about the early segment of the game with his first impressions video thingy, and i've been busy fixing most of the problems.
Here's a list of what v0.5.1 changes:

• fixed: the weird sound of the cars in the jump scene (intro)
  
• fixed: base's columns have working "target" indicators now
  
• "basic vehicle" and "fighter" drift much less, should be controllable now
  
• enemies from the first area shoot less often.
  
• enemies from the first, second, and third area have less HP (40%, 60% 80% respectively).
  
• softer thunder SFX (intro) ;)
  

i hope that fixes most of the problems with the early segment from the game :D

have fun.
