Planning new enemies and some lookback on code architecture

So basically I want to add new enemies to the game. They are probably gonna be some other teachers I encountered some time ago xD. The Game is working, but my code structure sucks so much and I am really not bored enough to refactor that piece of sh*t. That means new things I want to implement could take longer than they should. I have so many plans, and the game is far away from a release. I want a story mode, and add some Shading and probably rework the map. The Map is also still really small. And you know… a school is big. I hope I can make some progress in the next weeks. I have two weapons in the game right now and I really did work around much to get the swap system working, I need to rework my complete code architecture if I want to add a new weapon. The thing is that I started this project when I really didn’t have much experience with projects this size. The thing got way to complicated.
