Dealing with the rigidbody has proven difficult to me.
Resetting the player and the checkpoints system, other than that I'm very proud with the movement and the camera system.
Adding some UI, a multiplayer system, some rewards and make it so developing new levels is easier, it requires a reasonable amount of manual setup and some time to put things working.
It was very fun.
I put a lot of effort and I'm proud of the results. Hope you appreciate it and you have my word I'll put my 120% on everything I'll do if you decide to give me a chance.
