Hey guys, just came up with the idea for a blockchain-based game. I’ll be sharing the whole process here, from building to launch. Stay tuned for updates!

It all started with an old Siemens mobile game -BattleMail. A turn-based fighter where players submitted moves (even send vis SMS) and watched the battle unfold! That idea stuck with me for years, and now I think it could be fun to bring it to life.

The idea was to create a fighting game where players compete on-chain by submitting their moves. But I wanted to take it further - adding combos, super attacks, and more. Then came another thought: what if we had tournaments and events to make it truly competitive?

It reminded me of Rock-Paper-Scissors - both players reveal their move simultaneously, without knowing the opponent's choice. But how do you achieve that on the blockchain, where everything is transparent?

For the core game mechanics, I defined these basic specs for each player class:
- HP
- Attack Damage
- Counter Attack Damage
- Combo Damage
- Unique combo sequence

Attacks and defenses target one of 3 body parts-head, torso, or legs. Success depends on predicting the opponent’s choice. 
Counter attacks trigger when a defender blocks 2 hits in a row, damaging attacker. 
Combo damage activates when all 3 moves in a sequence land successfully.

Every player class has a unique combo sequence that maximizes damage when executed correctly. For example, the basic fighter class has a Head → Head → Torso combo. Timing these sequences perfectly is the key to dominating the competition.

The idea here is to bring chess-like strategy into the fight. Players submit their moves blind, without knowing their opponent’s choices - turning every battle into a mind game of prediction and counterplay.

In the first stage, I’m adding 5 fighter classes to balance the game:

Balanced Fighter – Well-rounded
Damage Dealer – Hits hard
Tank – Tough to beat
Counter Attacker – Punishes on counters
Combo Fighter – Big combo damage

First fighter class: Kabayashi. A solid, well-balanced fighter.

Next up: Gara – a tank with high HP but lower attack power. Tough to take down, built to outlast opponents.

Next up: Butch – a powerhouse with devastating punches. Every hit lands like a truck.

The solution was:
1️⃣ Player chooses moves
2️⃣ Creates a commitment hash (moves + secret)
3️⃣ Submits only the hash on-chain
4️⃣ After all players commit, they reveal moves + secret
5️⃣ The contract verifies by hashing again & comparing
The secret prevents others from guessing moves
