I made a 2d turn based rogue like thing for the GMTK  game jam.

What the actions do:

• Attack - Does  damage to the enemy, has a 10% chance to crit to deal double damage.
• Defend - Protects you from damage and makes you deal more damage the next attack (the extra damage does not stack) but has a chance to fail and the chance is higher the higher floor you are on.
• Loot - Loots chests for coins and heal potionsif there are any.
• Use heal potion - uses a heal potion to heal 3 hp, does NOT use up your turn.

These actions can only be done in the Shop:

• Full heal - fully heals you and the price depends on your health missing.
• Buy heal potion - buys a heal potion for 25 coins.
• Atk upgrade - Makes you do 1 more damage for 75 coins.
• Def upgrade - lowers chance of Defend failing and increases damage done after defending for 75 coins.

These actions can be done in The Anywhere Shop:

• Buy heal potion - A way to get heal potions anywhere, but costs 75 coins.
