The base is pretty simple, but it manages to offer some fun parts.
I liked the ice cube death :)
There are a lot of levels, but some are not particularly special, so perhaps you should have reduced the number to make the remaining ones more special. I was hoping for some jumps to do and having to land and slide quickly on the opposite direction when landing for example. I was happy to see the jump, but it was too much trial and error.
I also think it's too bad nothing pushed me to go fast (to encourage stupid mistakes), but instead let me do it slowly and precisely if I wanted. Some more craziness would have make this better in my opinion. Either just a timer, or ice breaking if you stay too much at the same location for example, or some wind gusts.
