Hey! Thank you for your feedback! This type of insight is exactly why I made this post. I am still developing the game and have been thinking about what to do next, I think that trying for making the units feel unique from each other is something that will definitely add so spice and maybe some fun mechanics, like CC little mini games.
Additionally the upgrade UI and the Ascension/Spell book UI will both be over hauled at some point but i was more focused on functional over pretty for now, I am not an artist so that will take me way longer than coding side of things. :) Thanks for you feedback, keep an eye out for updates in the coming days, maybe depending on the holidays.
Cheers!
