Thanks for the feedback. It's currently in development, but this is just a first beta of the game to showcase the project's concept. The credits and activation buttons don't work because they haven't been implemented yet. They were just added to prepare for a future update. As for the weapons, can you tell me which ones don't work? I need to add a tutorial because grenades are thrown with the right hand. Also, you're right, we need to work on the balance.
