Thanks! Weird... the ground is not basic texture. I made it using procedural texture nodes in the shader editor (Blender), combining several noise textures with different scales and a few color ramps.
The idea of the skeletons was they were hard when you face them alone, and easier when confront them with your buddies. But I should have added a attack modifier to the weapons too (which I will in the update).
I've played and rated yours. Great game!
