Very cute little demo! I'd definitely like to see this develop more over time. The one thing I will say is, I hadn't realized the range of the stopwatch was so short? But conceptually, I actually really like having to be near the platform to stop it. There's a lot of interesting platformer potential with that. Something to maybe consider would be to have a little circle effect that shows the radius on use, while also just being a cool visual cue to show you activated it. Also, I thought the text was really fun TBH and the ending actually got me. Neat game, and I'm looking forward to how you might update it!
