After reading reviews and what game staff said
Response from developer
I am sorry to hear that you are not satisfied with the review reply. The reply saying "you could beat level 2 without any spending" only because that comment mentioned level 2 in the title, it didn't mean you have to pay money to beat level 3. Thanks for your feedback and I hope you will give it a try.
Impossible to beat level 2 without spending atleast5 dollars
Response from developer
Thanks for your feedback! I am so sorry to hear that you were not satisfied with the game. Although it's not an easy game, I am pretty sure you could beat level 2 without any spending by applying strategies, like calculate the movement of both enemy and yours, make use of the landscape (especially the tent & city), decide who to take the last attack (more exp), save the game when taking risky move, etc. I hope you could give it another try and enjoy the game.
Good but needs work
