That's a really heavy file size for 5 minutes of gameplay. (Because yeah holy shit the unzipped file is nearly one gigabyte)
The level looks nice, I've never really imagined being right in the heart of a snowed forest!
As for the gameplay, well all I have to say is that the snowballs are like, really annoyingly hard to spot. They hardly stand out from the environment. First time around I thought that was a bug that took one of my lives.
Otherwise gameplay is ok.
