Really cool game! Great use of the limitation. If i had to mention something it would be the hitboxes of obstacles being really weird sometimes. You could've also used continuous collision checking to improve the physics a bit. Great job overall!
Thank you for your comment :) We are beginners with Unity, and the physics caused us a lot of troubles (at some point, falling from a certain high made the player passing through walls)... We did our best with what we knew ^^"
For the future, simply setting the collision to continuous on the rigidbodies will prevent them from going into each other, it will also solve the issue of passing through walls. One easy way to improve physics without much trouble
