Neat jam game! A few bits of advice:
The player controller keeps your current moving velocity whenever you leave the ground, and this makes platforming difficult if you make a slight input in the wrong direction just before jumping (which happened a lot for me). Being able to input direction in mid-air would help a lot.
The player speed is calibrated just right considering the size of the environment, but the acceleration could be a bit quicker. It takes half a second to go from standing still to full sprint, which feels a little laggy.
Outside of that, I was quite lost in the balcony section because it takes a bit to jump onto the railing. The capsule collider caused me to slide off an edge if I didn't land with more than half my character, which led me to believe I wasn't supposed to cross the balconies at all.
I would think about changing the collider to a cylinder instead, which has a flat bottom instead of the capsule's rounded edge. But, cylinder colliders can cause issues like getting stuck on walls if you're not careful, so I say use your best judgement.
Another way to improve the balcony section is to change the chair collision shape to a ramp. This would actually compliment the capsule collider you have now, while the cylinder collider might have some collision trouble.
Lastly, the jump reaches the right feeling height, but the gravity is very heavy and interrupts the arc which makes the jump feel unnatural. I don't have as much experience programming jumping, so I can't speak much to it, only that it doesn't feel as reliable as it should be.
All in all, I think you guys actually did a decent job. These are just some of my nitpicks.
Keep it up! :)
