Really liked the simple clean mechanic and the movement was pretty smooth. A little rough when getting up steps of the houses, but overall pretty good and easy to maneuver.
The thing chasing you and having to shoot it with what you collected added to the gameplay and was fun. Really liked the 3D environment a lot, it's really well made.
One way to improve it could be that when stamina is completely depleted and is being recharged it should change the opacity of the UI element to be lower, to differentiate for the user when there is no stamina because it was depleted by using it too much. Then it can be really easy to know when it is ready to be used again by the opacity coming back up to the way it is now in game.
Currently when it has been depleted, it's not possible to run again, and it's not easy to tell when it's ready to be used again by a glance of the UI. For now, have to keep track or assume you knew when you depleted it by running for too long and when it's about to be ready (usually when it's full or almost full).
Other than that really nice job on this game!
