New take on discard mechanic

🔁 Discard Mechanic Rework

• Previously, a pawn was automatically discarded every turn.

• Now, your storage and board start full with random units.

• To buy a pawn from the shop, you must discard something—so discarding is now optional, but a core part of strategy.

📦 Dynamic Storage System

• You start with 4 storage slots, but this number decreases as:

  • The number of pawns allowed on the battlefield increases.

  • You create triples (combine 3 of a kind).

• Over time, storage will periodically expand again, refilling with random units.

🛒 Shop Changes

• The shop now offers 3 choices instead of 4.

💰 Economy System Added

• You can now save up to 3 gold.

• Each turn, you gain +1 gold, or +2 gold if you win the round.

🎓 Tutorial Intro

• A simple tutorial has been added with screenshot-based UI callouts.

• Helps new players quickly learn the basics without interrupting the game flow.

🎨 Visual Updates

• Changed shaders for both characters and environments.

• Introduced a new outline shader to make characters stand out more clearly.
