Maybe it's just me, but I had a really hard time with some of the controls. The jump button seemed to work very intermittently, and I would have to spam the spacebar a bunch before Roboto would jump. I was also never able to get the 'T' button to work. These occurred on both the WebGL and downloadable versions. Weird!
Other than those, I thought what you made is really slick. It's clear the artwork and overall presentation and atmosphere had a lot of care put into it, and I thought the mechanics that were there fit well with the limitation. I'll come back later and give it another go!
