Here's my feedback on the game:
- Awesome concept, but I would like it if there was more taiga and less concrete (screen real estate wise).
- The art and music are really nice (good choice). Though, the concrete foreground isn't great.
- It is not clear that you need to kill (?) the red things. I thought that they were enemies that I needed to avoid.
- The movement is very slow, it takes too long to jump and change direction.
- The score and stars UI should be outside of the looking glass, to make it easy to see how much you have. How do you increase your score btw?
