Kudos to you for trying to work out comfortable Mobile controls. I feel so many games fail at this horribly because there’s no tactile feedback from a touchscreen like there would be from a key/button obviously.
Having said that, this looks promising. :D
Good visual feedback is one technique we use to try to overcome the lack of tactile feedback. Keep in mind that your mouse doesn't really have tactile feedback either for positioning, but you've gotten really good at putting it over a minion to last hit them. :D So tactile feedback isn't the only way to good feeling controls. I do think that movement controls are the most challenging ones to adapt to because you don't have the physical sense of where your thumb is relative to the center like you would with an analog stick. But you can always play on console if you want that experience!
