Hey,
The movement patterns are a really cool idea; maybe I can try to implement them.
I thought about the health system, but since this was a prototype, I decided to pass on it (since the game doesn't have enough content to be worth playing for such a long time). If I keep the project going, I will take it into consideration.
In any case, thanks a lot for your feedback. This is my first "game," so every comment is very welcome! ^^
