Welcome to Deku Plays Pokemon!

+

Instructions

+ The primary way to play the game is in the{" "} + + twitch stream + + . You can input votes in the chat, but first you need to connect your + Tezos wallet to your Twitch account. +

Step 1: Get your Twitch handle

+

+ Make a Twitch account if you don't have + one already. +

+

+ Get your Twitch handle by clicking your profile pick and copying it to + your clipboard. +

+

+ + You must enter your twitch handle exactly as it appears in the Twitch + chat, else it will not work! + +

+

Step 2: Connecting your Wallet to Twitch

+

+ Click on the button below to connect via Beacon. +

+

+ Once connected, submit a signed operation attesting your Twitch handle + by pasting your handle into the input box and clicking "Submit". +

+ {inputEnabled ? input_button() : connectButton()} +

Step 3: Connect your Twitch account to your Wallet

+ Go to the{" "} + + twitch stream + {" "} + and attest your TZ1 address by entering this command into the chat: +
+ !attest {tz1_address} +

Step 4: Play the Game!

+ Vote on the next move Deku will perform by typing commands into the chat. + Votes are resolved after each block - about one second; however, the + Twitch stream adds about 10 seconds of lag. +
    +
  • + The follow commands vote on the next input: +
      +
    • + !up - send input Up +
      • +
    • + !down - send input Down +
      • +
    • + !left - send input Left +
      • +
    • + !right - send input Right +
      • +
    • + !a - send input A +
      • +
    • + !b - send input B +
      • +
    • + !start - send input Start +
      • +
    • + !select - send input Select +
      • +
    +
    • +
  • + You can also vote on the governance mode of the game: +
      +
    • + !anarchy - Votes for Anarchy mode, where the first + vote received is the one executed. May the fastest gun win! +
      • +
    • + !democracy - Votes for Democracy mode, where the + majority vote received is the one executed. Long live + civilization! +
      • +
