good bones
-the matches are way too long. have at least 3 play structures: ~3 minute campaign missions, ~3 minute pvp, endless mode/raid mode where players fight until they lose once per week.
-create some more starter unit diversity, give players abilities to think about other than heal, shield, and pierce.
-once you get ~20 active daily users on your game, advertise. grassroots with youtubers, offer 10-20 small scale mobile gaming youtube channel with ~1000 views a video $5 and ingame currency to make a video about your game.
-once you get ~100 daily users post an ad on the app store and google play store if you're on there too. small campaign, no more than $200.
-once you get ~200 users pay one of those youtubers you like to make a 5 second and a 30 second advertisement for your game and post it to some of those mobile advertising services like tapjoy. don't spend more than $500 on your campaign.
-after you get 1000+ daily users focus on the player base. read the chats, adapt the game as you go along.
i hope you do well
