Pretty graphics and nice mechanics! Congratulations!!

I got to level 14 and what made me lost was that it started on the wrong side and at a location on the screen which I didn't expect so I didn't see it fast enough to switch side. For the rest of the levels, it is not so many side changes so you can often plan long ahead what changes to do meaning there is no hurry.

That said, it can be relaxing to play a game with just one button that is not to chaotic.

Easy and fun but one of the levels had part of the shape cut off so the corner wasn't visible

Well. It's okay and all, but I didn't enjoy it that much, since it kept resetting the game to 3 every time, I messed up.

Elegant simple graphics and a nice mechanic. Perhaps a 3-lives rule or something would help so you didnt have to start from 3 again each time you lose :)

This is very elegant, but not very challenging. Maybe if you had the tracks cross over themselves sometimes? That would stop you from just registering if the barriers were on the inside/outside of the shape so easily.

Really interesting premise and a great idea for the theme.

Not as challenging as I expected, but it's a good idea, well done. :)

An interesting premise but lacks any challenge or flair that would be needed to really come into its own

Smoother turns at the corners would improve the game feel a lot, also maybe the pause between levels is a bit too long. The difficulty takes quite a while to pick up too. I like qu2's suggestion that the track could cross over itself sometimes. I do like the simple elegance of the concept, it's definitely something you could make into a mobile time-killer with some more development.

Nice game! :) my score: 10
