thank you for playing. The browser build is a bit broken but it works alot better if you download the exe. The enemy pathfinding can be buggy in some cases, they are supposed to move to where they last saw you when you are out of sight and if you fire a weapon all nearby enemies will immediately move toward you so that might be why the enmy followed you behind the wall (Or it could just be a bug). I agree with what you said about the theme, my idea was to incorporate the theme into the gameplay itself by having enemies move in predictable patterns (unless you get spotted) and the player can try different strategies every time they retry to complete each level.
