 ## bomberman-dom
 
-You certainly know bomberman right? Good good. You will make it. Relax, is not that hard, it is only a multiplayer version of it. Ah and forgot to mention that you will need to do it using the framework you created a while ago. Let me explain.
+You certainly know [bomberman](https://en.wikipedia.org/wiki/Bomberman) right? Good good. You will make it. Relax, is not that hard, it is only a multiplayer version of it. Ah and forgot to mention that you will need to do it using the framework you created a while ago. Let me explain.
 
 ### Objectives
 
-For this project you have to create a [bomberman](https://en.wikipedia.org/wiki/Bomberman) alike game, where multiple players can join in a same room and battle until one of them is the last man standing.
+For this project you have to create a bomberman alike game, where multiple players can join in and battle until one of them is the last man standing.
 
 ### Instructions
 
-When the user opens the game, he/she should be presented to a page where he/she should enter a nickname to differentiate users. After selecting a nickname the user should be presented to a waiting page with a player counter that ends at 4. Once a user joins a room, the player counter will increment by 1. As soon as there are 4 players in the room, the game starts.
+In the beginning there was 4 players, and only one came out alive. Each player will have to start in the different corners of the map and only one will be victorious.
 
-#### Beginning of the game
+You will have to follow more a less the same principles has the [make-your-game](https://public.01-edu.org/subjects/make-your-game/) project. But we will refresh some of the concepts you will have to respect and deal with.

+1. [**Performance**](https://public.01-edu.org/subjects/good-practices/), is one of the most important aspects while developing a game, so lets respect it.\
+   Just like make-your-game you will have to respect the policy of:
+
+- Running the game at least at **60fps** at all time
+- No frame drops
+- Proper use of [**`requestAnimationFrame`**](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame)
+- Measuring performance to know if your code is fast
+
+You must not use canvas neither [Web-GL](https://get.webgl.org/) or other framework, for this project you will use the framework you did on the [mini-framework](https://public.01-edu.org/subjects/mini-framework/) project.

+player counter will increment by 1. As soon as there are 4 players, the game starts.
+
+#### Game Mechanics
+
+1. Players
+
+   1. Nº of players: 2 - 4
+   2. Each player must have 3 lives. Then you are out!!
+
+2. The map should be fixed so that every player sees the whole map.
+
+   1. The maps should be generated randomly. There will be two types of blocks, the ones that can be destroyed and the the ones that can not.
+
+3. Power ups (each power up must appear randomly after a block is destroyed):
+
+   1. Bombs: Increases the amount of bombs dropped at a time by 1;
+   2. Flames: Increases explosion range from the bomb in four directions by 1 square;
+   3. Speed: Increases movement speed;
+   4. Bomb Push: Ability to throw a bomb after it has been placed.
+
+This project will help you learn about:

+- [`requestAnimationFrame`](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame)
+- [Event loop](https://developer.mozilla.org/en-US/docs/Web/JavaScript/EventLoop)
+- FPS
+- [Jank/stutter animation](https://murtada.nl/blog/going-jank-free-achieving-60-fps-smooth-websites)
+- webSockets
+- Synchronization
