I know I've complained about the unit list before but...after buying enough units with silver, going through the unit list is like navigating a maze in the dark with a candle for lighting. It's not only confusing due to the lack of sorting but also incredibly limiting to only be able to see 4 units at a time. Otherwise, I do like the gameplay thus far.
I think this game needs some improvement in sorting for the card merchant. Specifically, I'd like to see sorting options such as sorting by ally type, rarity, and card cost (Resource Cost).
Suggestion: Make deck building quicker by either allowing us to add more than one card at a time or make it so it only takes one click to add a card.
As it stands, building a deck from scratch is tedious and annoying due to having to click a card then click add every single time. "Tedious and annoying" are words you never want used to describe any aspect of your game.
The main focus of a tower defense game should be the towers' reliability. I've literally watched an entire line of creeps walk past my mage tower without it firing a single shot because the creep it was targeting gets out of range and it goes on cooldown constantly.
Furthermore, towers should not go dumb when another tower kills something it was targeting, they should transition to the next target without triggering tower cooldown.
Unreliable towers ruined the game for me.
 "Global Assault"){kind=icon}
 "Shadow Era"){kind=icon}
 "Horde of Darkness"){kind=icon}

Thanks for the suggestion.
