Ohhh i really like this, the style is great + it felt pretty balanced for a demo, i was able to 100% everything without feeling like i was overflowing with useless items, which can sometimes be a problem in these types of games. XD
My only criticism is i think the auto click option would be a lot better if it were able to be triggered with a click. If you're trying to be optimized, it can be frustrating for it to just automatically click constantly because lining up your clicks can really matter if your stamina is low, but if it were activated by clicking once and then could be deactivated with another click until you line up where you want it again, that'd be a lot more useful?
