A great story — the idea of “arriving too late” even with the power to stop time was very well thought out. I really liked the models you used and the animations you included, especially during the running sequence combined with the sudden camera movement, which created a very engaging sense of immersion.
Personally, I enjoyed the sound effects, but I feel the music didn’t quite fit the atmosphere. This may come down to personal taste, but I think something more dramatic and intense toward the end would better convey the devastating feeling of helplessness the protagonist was experiencing in that moment, knowing there was nothing more she could do about what had happened.
One thing that could harmonize really well with your scene would be having the background music playing continuously while the character hasn’t stopped time, and then, once time is stopped, the music would stop as well—just like the objects freezing in place. This would give the impression that the character’s power is so overwhelming that it can stop absolutely everything, which would make the final moments of the scene even more tragic.
Overall, it’s a beautiful tragic story showing that even one of the greatest powers can’t do everything. Great work, and I wish you the best of luck in the jam.
