Wow! This is amazing, the polish is soo good, great job! I had some problems with the player moving and picking up items, but these are just minor. Overall amazing work for 2 weeks, the enemies felt threatening, and the story was acutally pretty good. After I read the introduction to enemies, I felt uneasy and open for attack. The enemies also always felt like a threat. Did you implement a dynamic difficulty system? It felt like it, because sometimes the enemies tanked more bullets and sometimes less.
Overall great job, I love it!
