Well, I tried really hard, but I couldn't get passed the first level. The jump felt way too imprecise, sometimes it wasn't high enough, sometimes it just wouldn't trigger... Even the tutorial was hard. The last part of the level after (when you have to jump vertically several times in a row) was simply impossible for me to pass.
However the idea is good! Using obstacles to bounce feels great! Especially when it allows to gain speed. With some tweaks in the evel-design or the physics, it could feel really great to play! Plus, the minimalist visuals are pretty nice. It's still a very interesting entry!
