Wow. I'm surprised more people haven't given this a shot. It seemed like a game everyone would enjoy.
355,500 here, but plenty of room for improvement (I lost all of my lives fighting this giant woolly mammoth boss that I did not know the pattern to
). I think I'm a fail at game choosing
Tips: Definitely try and get a good weapon and stick with it. Wheels are the best IMO.
Always "charge" you attack even when there is nothing on the screen. Abuse the charge attack
Try and collect all the food you can. It give you more points and heals you. This means killing enemies where you can get to them.
Go mario and jump on the enemies that you cant kill in time and will hit you (this includes boulders)
There are youtube videos of people beating this game on one life if you need some more tips.
