Oh that is interesting and should be concerning. Some enemies as time goes on they scale their HP which means that they require more than one hit to kill. I wish we had time to make this more noticeable but for now it just pops up with text whenever you level up. Our intentions were to release this game on mobile once it's ready so we are happy to hear that the concept translated all the way through and that you found it fun and enjoyable to play on your touch screen! Hope to see you when we release our build on the play/app store! :D
