Sorry for the long update. Because we are having trouble to create our own assets and also create our own script.
So, here we are.
Today We managed to create the prototype of the game.
In this prototype, the gameplay is explained. Player can move right or left, jump, attack (melee). There will be enemy that patrol in a platform. When you fall, then it is game over.
This is the controller (since we have not applied the User Interface yet) :
move left = left arrow
move right = right arrow
jump  = up arrow
attack  = left ctrl

Next we will add some new features. First, we will update the character and of course, more sprites animation. The game will also have UI that describe the gameplay. Enemies can attack and reacts to the player. However, we will change the story a little bit to make the game simpler. 

Thanks for reading this dev log.
