The experience itself isn't all that bad, takes some time to start working towards building a decent team. The main concern is that the game constantly encounters bugs that reset progress. Sometimes having to fully stop the game multiple times just to fix it, and by that time I'm already annoyed with having to do everything multiple times over (upgrading runes, prestige, watching ads, trials, etc.). Everything gets reverted each time the game bugs out, and it enters a "soft lock" state.
