New dungeon game experience, has a large room for improvements

This kind of dungeon defense game is new to me (All I know is tower defense). It piqued my interest in a nice game that needs improvement. I am gonna list below my experience.The art and the game itself are good but not great, need improvement for sure.

The tutorial is explained well so the game flow is smooth but some text needs to be looked at. I liked that it has an hourglass that can be acquired when watching an ad -- it was a good choice. The plot is good with comic-style yearly chapters. My interest started here.

Having to think about what to upgrade every successful defense is a nice touch, but the UI is a bit clunky or has too many clickable variables. One advantage of it is it can be played offline.

Though, the gold and item rewards can be improved. Its UI needs improvement (just nitpicking), and boxy needs an accent on the edges. Look into some texts and you can see some </br> and others are not translated yet. Can also improve the hero's armor.
