Why even have you hold the spacebar down. Games that have an mechanic with no drawback that you never stop doing should be by default "always on."
This game needs to be mouse-controlled. This simply change to analog control would take it from being a poor excuse of a shooter, to being a great and enjoyable game.
I like this. It's little silly fun games like this that keep me coming back to Kongregate. Things without any sort of real time investment that are stylish and I don't have to read the instructions for. 5/5
5/5. To get Solo Star, you've got to budget your experience to space out levelling up. Your fuel runs out unless you level up. Go up too quickly and you won't have refuels later when you need them to get the big money enemy upgrades.
Secret is to go long as possible without getting hit, it resets your multiplier from 1000 pts down to 50 pts. Gay score submission: had to do Hard Badge twice to get it to register.
Short controlled bursts with the uzi owns. Two bullets at a time at the head of any enemy will likely take it out. You'll rarely need to reload. Much better than emptying your clip into fat farmer gut. Pistols > either rifle or shotgun, clip too small even with lots of survivors. Stockpile at least 9 supplies before getting to Jonestown, then click it, go back to travel screen again and click Union to win. Zombies won't damage barricade until they land a blow, they wind up obviously and slowly so budget your shots and timing. Always reload when a bunch of slowpokes are on the screen so you'll have enough ammo for when the runners come out. Chainsaw is a good upgrade from the pistols until you get the automatic weapons, if you have survivors to arm. Arming survivors with automatic weapons is a waste, they only fire one bullet every 4-5 seconds.
