The concept is good and the graphics is great, there is one problem, and it is a big one: 10 stages in a row, without a possibility to exit and do something else is huge ergonomics issue. This is a mobile game and getting 10 stages can take up to 30 minutes. This is more than a normal person can do on a computer or a console at once without getting frustrated or tired. My hands literally hurt from working the phone or a tablet screen with such intensity. It is also incredibly frustrating when you die on stage 10 after 25 minutes of gameplay. The other game, the expedition is only 3 to 5 stages and you can heal in between, or exit and play other modes. Consider either shortening the stages, or giving people real breaks in the middle, where they can do something else in the game, and not jus pause it.
