Other the bug that you mentioned, I only find a bug there you press E fast enough at the orb statue to make it so that the text box appear twice.
Gameplay wise, so that its easier to be played, I think turning of the collider between allies would be a good idea. Sometimes, your allies would just body block you in the corner and get in your way. Additionally, currently the controls are very focused on the left hand, whilst the right hand only be used for clicking UI. I think it would be nice if you can either balance it out between the hands, or just remove the mouse controls completely and focus solely on keyboards (just odd that you need to use mouse so little just to move on the gameplay and not used again until the next UI buttons). Maybe making targeting the mouse job (using ray casting)? It would make it easier to target too, since right now, you would need to start from the first character (aka you) and press Tab until you reach the one added the last.
