What immediately stood out to me was how beautifully put together your aesthetic was. The little story bit was fun. Do you plan on adding more? The music fit and the art was cute. Did you do all the art yourselves? If so, great job!
Physics puzzlers can be quite fun, but seem to be difficult to get to a point where they "feel right". You set yourselves up for quite the challenge! Great effort! It still needs some work to make it feel fun and intuitive, I think. The creativity on those "hazards" or whatever those were was quite cool, albeit also frustrating.
Also, I think some nice features you could add could be: - A skip button for the timer, if you feel satisfied with your set up - Some in-game control explanations - and maybe some sound effects for inputs and the timer.
All in all, a well polished game, great work!
