Okay, I just got confirmation that this "developer" is an imposter. I have no idea wtf his goal is. Anyway, just ignore this. I will report it to kongregate stuff.
It's hard to describe the damage of the weapons, I'll provide a few numbers here and hopefully that helps:
Spray shower: 24 damage per bullet, at level MAX you're shooting 9 bullets every 1/15 seconds. That makes 135 bullets per second, making it 3240 dps (damage per second) but not all the bullets always hit.
Random Blitz: 41 damage per bullet, at level MAX you're shooting 22 bullets every 1/15 seconds. Random Blitz is hard to calculate dps since you're expected to miss a lot of bullets and hit multiple targets at the same time.
Straight Shot: 21 damage per bullet, at level MAX you're shooting 6 bullets every 1/15 seconds. That makes 90 bullets per second, making it 1890 dps and straight shot is easier to hit your target completely since the bullets don't spread much.
jdizzlean: Your first observations about having autofire on and shopping in between levels are totally valid and it was just bad decision on my part not to have made it that way. These things will definitely be worked on in my future projects.
Regarding difficulty, you do get more money for playing higher difficulty. The amount of money you get is based on your score and you get more score on higher difficulty.
hey nhoojn, I'm glad you like it. What do you think needs to be fixed? As for the bonus percentage, the more lives and bombs you have in stock, the higher it can go. Also, the more you die and still manage to survive can potentially increase that greatly as well.
