This is a really cool idea! The controls and graphics just feel right, well done. My only criticism is that the obstacles feel a bit boring after some while.
Interesting little casual game with a clever gameplay which fits with the theme. Minimalist. I had fun playing, but my score is not really really good. Well done! PS : as a compo entry, you Have to share code source. It's not for grab something, but respectfully it's the rules for everyone. I wish you the best ++
The obstacles felts like I should have hit them a few more times than I actually did; perhaps they could be made bigger.
