Played one battlefield. The shop reads well: five cards, HP and ATK on each, and the quantity row with 1/2/3/4/MAX right beside the Roll button, so buying a squad is two clicks instead of five. Starting at 500 gold with a 1 gold roll made me reroll more than I expected, which is probably the point. The blue deployment zone being called out in the shop header is the kind of hint that saves a first-timer. On your feedback list: gold pacing felt generous at the start and the towers were the thing that actually set the clock for me.
