This really creeped me out but I managed to beat to the first level and half the second level. Normally I wouldn't even give horror games a chance but I like this one because the mechanics were easy to understand. The monster was really creepy and I would feel icky whenever it got close.
I like your take on the theme to be freezing movement and not just freezing cold.
The parkour controls felt really good. Expanding on it to have more chase and escape sequences could be really cool. Well done!
