The graphics are great and so are the music. I like the simplicity in it, there is nothing complicated about it.
BUT - there are some things in this game that I find very annoying.
1. You didn't make a tutorial.
2. When it comes to the robot - the smallest ring bugs and the precision on getting it right wasn't fun at all, and that you have to start over again isn't fun. :(
I usually have a lot of patience when it comes to gaming. But I didn't have the patience to complete this. Maybe it wasn't suited for me, but I wanted to make a rating anyway and hope that you might find this helpful in some kind of way.
But keep up the good work!
