NEMO

[ 日本語 ]

※ it's beta for now

A functional game engine that can create emoji games.

Major Features

• Easy to create games with powerful functional languages ​​(PureScript).
• Only emojis can be used as materials. Instead, there is room for creativity.
• JavaScript knowledge is basically unnecessary. You can concentrate on implementing game logic with functional languages.
• You can play on any device on which the browser runs.

Why PureScript

When making games in functional language, there were the following options.

Haskell -> If everything could be done with this, it was the best. However, it is difficult to play on any device.

Elm -> It was one of the good options when thinking about device independence. But there is no type class support. It is also recommended that you follow the Elm architecture.

PureScript -> There is type class support like Haskell. It will also be compiled into Javascript. Therefore, you can play on any device browser!

Why Only Emojis

Something restricted stimulates creativity.

I was very inspired by fantasy consoles represented by PICO-8.

There are severe restrictions on sprites, sounds, capacity, etc. that can be used.

On the contrary, These constraints inspire creativity and making the game more fun.

Just like this, I think that it is very interesting to have constraints that only emojis can be used in the Web platform.
