I like this concept, but there's several parts I didn't like in practice. Like other commenters, I didn't like the camera movement. I think this would've benefited more from have the dog being the parent of the camera and crafting the dog's movement around a comfortable speed/acceleration instead. Besides that though, the items were constantly too close together. I think having them be thrown off from defeated orcs would've made it much easier to grab individual items. Lastly, it feels oddly subject to RNG. I got to level 2 and failed almost immediately because no health potions were dropping at all.
All that said. I do think the visuals are surprisingly functional given how clustered together everything is inevitably going to be in a game like this.
