Neat project! Unfortunately its really hard to tell what the control scheme is, and the remapping page is blank so I couldnt even tell what actions were available to me. the turret on the right seemed to reload regardless of my proximity to the reload button, and I could not get the upper middle turret to operate by pressing any keys in the room with the "shoot all" banner.
Art was great and I liked the idea of actively managing a tower defense! Would have liked either more feedback (ie a sound or visual when you interact with something) or perhaps even a short written explainer.
