Thanks a lot for the feedback! You're totally right, you can rush straight to the core in the early levels since I made them easy on purpose to teach the controls. From level 3 onwards, the battery drains way too fast to just sprint through (friction only charges you at high speed), plus the polarity arcs and moving magnets start blocking the direct route. I've been thinking about adding obstacles, though, I just worried it might get too frustrating in the advanced levels😅
