Excellently executed on the concept and mechanics, I really like the idea of scaling the length of time and not just the size of objects! I did get stuck on Level 9 and couldn't figure out how to progress, but everything else was really well done, I especially like the Portal vibes. If I had to give one critique it'd be that the feedback for scaling time wasn't clear/strong enough. Even with the subtle vignette change it didn't feel too much like stuff had happened
