3rd Entry (Item/ currency)

Hello again, I'm back with another update for my college assessment 'Tyranny England'. As I said in the previous post, Tyranny England is a college assessment where I have to make assets for a game based in/ about England.
Today I'm going to upload some currency items that will be available in the game, I only have one type of item for currency but three different versions, here they are:

The purple at the bottom is the "obsidian gem" and is worth 5 coins

The blue gem in the middle is the " Turquise gem" and is worth 10 coins

The red gem in the middle is the "fire gem" and is worth 20 coins

In the game these items will be called gems and provide the player with currency which will allow the player to buy upgades, and items that will help the player progress through the game. I need more ideas though for varying currency.

I know it's only a small but it's a start, this is the end of the 3rd entry, I'll post soon, bye
