I was a bit invested at first but having to inexplicably stop every few seconds with no way of preventing it makes it a bit unplayable, it wasn't fun at all. But I do like the backgrounds and the decision to make it look 3d. Maybe next time it would be good to include an indicator so that the player would know how much energy they have lost or a timer that they can prevent from going down to 0 to make it more interesting. Regardless, congrats on your game!
