I'm a little bit confused by the mechanics. I think the instructions are backward. At least, pressing J to fire consumes my armor and spreads the shot out, whereas the instructions suggest that pressing K should do that. I'm also not sure why I keep dying when my armor is at 80%. Still I like the parts I understand a lot. It makes for an interesting strategic tradeoff. Maybe it could just use a tutorial or at least an easier level 1.
