I'm new to this. I'm working on my first game - escaping from a bad guy trough a random generated tunnel. The monsters' speed depends on the difficulty, tunnel width and it slows down depending on how sharp the curves are. Haven't put a lot of work in the appearance yet but just wanted to put this out here to maybe get a few opinions on whether it could be a game people would be interested in. Also suggestions for cool improvements, features, designs and so on are very welcome.

If you have the time, please do give an honest opinion on the gameplay.
