The game project I really want you to make is
:star:︎ A game where you have to reach the bell at the end of the single wooden bridge 80 meter of the building.

:star:︎ Pull the string to ring the bell.
↓ ↓
:star:︎ Return to the starting point.

This is the end of the game. Do you have a similar template project?

In addition, If you can do this.
There is a plank on a jungle cliff.
Looking down from the bridge, it is clear that
if you fall into the abyss, you will die.
At the end of the bridge, there is a small cat stuck and trembling.
I want to go to the end of the bridge and pick it up and bring it ,
but a gorilla appears from the cliff on the other side and throws bananas
and fruit and gets in the way.
If you defeat the gorilla and bring it back, the mission is complete.

I am looking forwards to you lovely.
Thank you.
