Jack 1.3

I finally solved a gameplay element that has been plaguing me for some time. The enemies now notice if you are behind them, and they will start shooting at you. it seems like a small change but in reality, together with the fact that it is no longer possible to touch them without dying, it has also involved changes in the structure of some level. places where access was previously possible were now impossible due to more intelligent enemies. the final version of August is approaching but it will only be a few cosmetic changes.
