I dont know if this was some problem with my specific pc but I couldnt do much because moving the mouse a few cm would rotate the view completly, I tried to set my pc sensitivity to low but it didnt help much
I also think the player´s attack should be more obvious, there not crosshair and the kunai (?) disappears almost immediately
Other than that though it seems like a pretty cool game, from what I could see it had quite the world to explore and I like the upgrade scripts
