Thanks for the comment! I spent a lot of time 3d modeling almost everything in blender.
1. I assume you aren't playing on windows. If that's the case, then it's an issue that constantly happens with my look code that I don't know why it happens.
2. I realized that bug when I was exporting my game, but I didn't have any time left (it was 2 am in the morning) so unfortunately the bug had to stay.
3. The best way for the robot to stop following and attacking you is to get the robot closer to another scientists than you. Unfortunately I didn't take this into consideration when first implementing the robot, so that will be fixed in later versions.
