Thanks for playing! Yeah would have liked to get some sort of tutorial made, tried making a small description "tutorial" when you press the tutorial button but even then my friends playtesting got a little confused. So definitely something that could do with improving. Idea was you have a thre types of machines, one that generates a bullet type, then another that applies effects to your bullets and then finally when you want to shoot the bullet you connect it to the cannon type machines and they are colour coded but never explained. And then you left click to shoot once the cannon is filled with the required amount of bulllets.
Overall there are quite a few steps and arent really explained all that much apart from a tutorial button on the automation UI which is easy to miss, so definitely something i'd like to work on.
