I am not sure if intended. but sometimes you on/off autoshotting when buying an upgrade.
like I buy an axe upgrade and it starts autoshooting. if I buy another axe upgrade the autoshooting may or may not turn off.
same for knives and mages.
only the arrows are completely manual, each click one arrow.
in the end, there is just a machinegun like level of axes being shot to the point where enemies die on the right edge of the screen :-)
Yeah the autoshooting should stay on, that's a bug. It has something to do with the engine having a hard cap for objects in scene.
We probably should have created the projectiles as some kind of particle instead of objects, but we wanted to test the limits of the tool (and that we did).
Thanks for playing our game :D
