I loved exploring the different train carts! The art was awesome and I really liked the differences from each area. I would have loved to use the guns seperatly to fight the enemies (and sometimes felt like I did), but the dual pistols were a good touch. The enemy animation is nice too.
The audio and art style made me feel like I was 10 years old trying Bioshock for the first time. Very cool, kinda creepy. Good job! I would love to see what the pieces I pick up do!
