Описание на английском языке (изначально постил на upwork):

It's a multiplayer PvP game, where you fight your ram to become the strongest one and maintain your rating positions.

- screen 1: choose ram and your avatar, two types of Ram (fasty and weighty)

- screen 2: loading screen as match is being found for multiplayer

- screen 3: match found, battle to begin

- screen 4: battle ground, both rams shown on the screen

battle mechanics:

-the battle ground is 2D

- there is no restriction on where the ram can move to

- the ram can be moved wherever you drag it to

- the battle will last for 30 seconds only

- there will be a bar that will charge when you touch and drag your ram back.

- The charge bar is 600 px width. Moving Fasty back for every 100 px will fill the bar with 50px. Moving Weighty fills it will 30px.

- Fully charged bar hits with 100% power, 10% deals 10% hit power.

- If you strike three times in a row, your damage is 10% increased.

- Weighty is Big & slow, 400 hp, 10 dmg.

- Fasty is small & Fast, 100 hp, 40 dmg.

- after the end of 30 seconds whoever has more HP left wins

- screen 5: battle finished, winner shown on screen
