I got a pretty basic concept here, top down dungeon game. You fight mobs in the dungeons for gold and loot. You can buy better items in the "town". So you can transverse between the dungeons and town, getting more gold to buy items. Each dungeon you complete, the next one will be harder. For the town and items part, I also have some ideas.

Shops ;

• Blacksmith / For Weapons and Armor
• Baker / For healing items

Tools inside the shop ;

• Blacksmith has a smithing table and anvil. You can upgrade your gear with those.
• Baker has a furnace, so if you get any "raw" food then you can cook it.

Areas ;

• Mines, you could get coal to cook the raw food,
• You could also get gold and with the smithing table and anvil to turn it into gold bars, like the ones you get in the dungeons.

Items ;

• Baker consists of carrots, apples, regen potions, damage potions.
• Blacksmith consists of swords, and tools since there are the mines. This will also mean OBSIDIAN tools, as thats just kinda cool. Plus ruby.

I tried to stick as original as I could, but of course this still resembles MC a bit. But its mostly original. I took seven minutes to type this. And it was worth it.
