Maybe falling off is a bad way to get over walls
Maybe programming games isn't your cup of tea.
The controls are terrible (even when you can configure them, that's saying something), and the combat is way too clunky. There is no hit detection for the wall in the first level, clipping is everywhere, and jumping once takes you across the map unless you're planning on jumping VERTICALLY.
You make a game that looks like its supposed to be based on stealth and yet you can't sneak up on anybody (no matter how low that sound meter to the right is). She is in the middle of what seems to be Siberia wearing next to nothing, and the temperature of the air is 23* C? And it's snowing? nope. Maybe its her body temperature, oh look, hypothermia is classified as body temperature below 35* C. While it's possible to survive low temperatures, wearing next to nothing in said temperatures and running around being stealthy is probably not likely.
I used to follow you guys long ago when you were still working on the Perfect Kirby series, and I think you should probably go back to making movies instead of making games.
Also, I've always been a fan of your pervy sense of humor, but you may have taken it a bit far with the money pickups (oh she works hard for the money)
From what I saw in the first level, which I didn't bother to complete due to not being able to see where I am supposed to go after climbing the cars, the main character is a stripper that got lost in the Russian arctic and is having hallucinations due to the extreme cold and the lack proper clothing.
