Mathematically speaking, yes, but it's extremely difficult! You need to memorize where all the stains are, map them out, and try multiple times, even as the developer, I haven't been able to get past 87%. There are specific power-ups that spawn around the map to freeze time and boost player speed, plus a secret bonus. There's also a secret area with stains that you must discover to reach 100%. It was intended to be hard, though maybe it ended up a bit too extreme; for a time attack, the goal was around 90%. Thanks a lot for playing and leaving your review!
