## Specification

The goal of [the sequencer](https://hackmd.io/dlix1pGmTRm61ODH3kkDzw?view) is to produce a sequence of operations. It means the sequencer will have the ability to reorder the sequence of operations or to censor operations. We are using this [Sequencer source code](https://gitlab.com/marigold/pistachio/-/tree/pilou/sequencer).

### WASM Kernel

Let's define all of these features in a single file `lib.rs` in the beginning.

a. [Storing the Dungeon Map](https://hackmd.io/cNjIsEpXTIyaVxUSEOS75w)

b. [Adding the Adventurer](https://hackmd.io/58vFHzOFRriUo_whgbIHtg)

c. [Add Inventory and Power-ups](https://hackmd.io/iPI_tVcNR3KxpzFzfGbKlw?both)

d. [Interact with the tezos-smart-rollup kernel](https://hackmd.io/bTy9Xww1Thm6xnvxCvxwog?both)

e. [Optimizes the implementation](https://hackmd.io/B_KPllVoTkGiHNEpYcFxTQ)
Split the `lib.rs` into modules.

f. [Connect player with wallet (without verification)](https://hackmd.io/gKZlr2deTyqSrHOkPiYY_A)

g. [Transfer items (drop item)](https://hackmd.io/9JhErqRZR-eupfeoA6rfeQ)

h. [Market place (buy and sell item)](https://hackmd.io/Ch8fy2zhSOOg7WbJoCmcEQ)
