Overall, I love this game. It’s easy to comprehend yet exiting and fun to play. The idea is cool and I love how it plays out. The main issue I have with it is the fact that the game gets somewhat boring after some time. If you play for more than 10-20 minutes at a time, it gets very repetitive. If there was more progression than “+n (troop)” and “+n% _____ effectiveness” then this game would definitely get 5 stars. Maybe add more types of troops or add ways to upgrade them BUT not like every other game where you open up a chest and get x y and z once it finishes. My recommendation is that you make it to where at the end of every game you get to chose between 3 random packs, all of which have different cards inside in order to upgrade. One major plus to this game is that there are no ads whatsoever. Perhaps optional ads could be added for more rewards so there’s some room for income in the game. Overall, great game and i recommend it.
