Excellent visuals and feedback for your actions! And the background ambient music is pleasant enough to still be enjoyable after 20 minutes of gameplay. Oh and I almost forgot the engaging dialogs, I really had a great time reading. The game is obviously super polished! Well done ;-)
The next thing is not specific to your game, but rather most of the games in this genre. I think the game lacks meaningful choices and things you can really learn. I found myself buying stuff while I didn't really know which one was the best and I'm not even sure there was a true difference. As long as you keep investing (and clicking a lot) I think you're good? That's my feeling after finishing the game at least. My point is I would love to see such an addictive and masterfully crafted "package" put to use in a deeper, more challenging game. Please? :D
