+ Progression feels good + Ads optional - Performance, major battery drain and locks up forcing a restart as often as every 2-3 runs, losing the current run. - No cloud save, I reinstalled after the dev response and had to start over. - Talents need a notification similar to missions telling me when I need to look at them... how far to next level? - Several UI boxes feel like they should be scrollable and aren't leading to cutoff elements, see: talents, skins Edit: Forced ads were removed.
