Interesting idea but it seems like it requires a bit of polish.
I encountered something weird where my character just couldnt go right (it only happened once and fixed itself shortly after)
Standing at a door and holding left click you are basically immortal early rounds
Doors are very hard to find so I basically just circle around the house until my character enters the house
You can attack through walls
But the idea is definitely there, and I encourage this to be continued to be developed with some extra buffs and upgrades and more stuff to loot around the map it could be an interesting mobile game
