A game design idea:
- Plants of different colors. Every color is a plant usage type: weapon, XP, potions etc.
- You need consumable items to deal with plants, collect them and learn their effects.
- So, you are limited with consumables and have to choose which plant to examine
Another idea:
Why do you need plants? Maybe you are an alchemist, or mage, or pharmaceut. And you have a shop. And to craft goods and learn new stuff, you need to explore the Dangerous Caves of Unmercy Doom. I mean, game can be much better if we really care about all this herbs. If they are not just obstacles, but desirable items.
At the moment, the game has nothing but nice style.
