This game was so much fun to start with, doesn't require much concentration while I'm listening to music/podcasts. But once you reach level 7 and move to level 8 there's very little to do, no quests, no engagement just moving around in a loop trying to meet the unrealistic next level xp requirements. Add more quests and objectives! un-installed

Kills your time, strategy as well. Free to play, no forced ads, works offline. Map is organised, good dynamics/physics. When you think you finished game, new winter area opens up. Alien constantly evolves, and your orientation and memory. When you hit impossible and you're about to uninstall, you still find the way. You think you cheat game by AFK playing, but game cheats you, so you play more to realize, OMG, I'm addicted and need to run this game 24h/7 to win, smart. Game finishes post 15lvl

The only thing to do in the game is events and they are impossible to complete. You need 3 or 4 solid days of 40 hours to beat them. You have to constantly reload the game to get event items to respawn and now when you open the game it does 5 or 6 pop ups. It was fun while progressing but now it's just waiting for the next area in the new zone to unlock and do events. Events aren't remotely fun so I'm going to uninstall now
