Pretty nice/simple concept...I guess
I don't think I've ever gotten bored so fast, it was way to repetitive, easy, and it takes forever to get the boss. There's no surprises/easter eggs to keep you entertained, or medals to persuade you to push through.

A bad game that could have been okay. Here's why:
The mouse controls are annoying.
Once you wake up the boss, enemies suddenly gain 200% health.
Getting full upgrades (mainly Muzzle) is impossible.
Also, I maxed out both the Money Magnet and Gold Hustler but they were still too weak to be worth getting.

Interesting controls, not hard to get used to. Challenging but not too hard if you have a few restarts and some patience. Well done

not bad. in fact, when I played it for the first time, I didn't stop before finishing it. however, I feel there should have been some stages in it. moreover, bring in some story line (the concept is good, btw) and some medals.
overall a nice effort. make an improved sequel to it.

Really fun game, I just don't understand the energy system. I woke the boss and got him down to 30% and died. All that work gone. :(
