I liked the simplistic design... but the jumping/running combination was very confusing. I kept running when I intended to jump (I have a tendency to keep my finger pressed on jump). Also, sliding up the wall was not intuitive to me. I either kept getting caught running instead of jumping, or I would end up wall jumping instead of sliding up. With that timer that kills you, I never had the time to get used to the controls. Sadly, I became too frustrated to even get past the tutorial level. Sorry
Loved the music though!
