Simple 2D graphics are a very popular solution.
The fantasy setting is a very popular setting.

Gameplay
{
Another tower defense game is a good idea!
Resetting a player's level is not a convenient, discrediting idea, please spare the players' time, we must have a personal life.
Blood as an element of volute is a good idea, the main feature of your game is good.

Thanks for making this game!
