Ohhh i see the problem. The original shoot key was ctrl, (both ctrls), after uploading the webGL version, 30 minutes before deadline, i saw the ctrl problem, so in a rush changed the controls to Z and M for both players, but forgotted to change the clones, i reuploaded a version seconds before the deadline with the clones changed, but apparently i missclicked one config.
The intended way was both players and clones can shoot with the same key, Z or M, currently the clones shoot with Z and ctrl, sorry for the inconvenience
Thx for the feedback!
