He got a good point. Your work by now is already incredible. I've been searching for games like yours for some weeks now and I found nothing similar to Welcome to Erosland. The artwork, scenes, history, evolution and management is so good. I easily would pay 50+ U$D for a final version without complaining.
Also, taking the best of this review, some girls with more evolution and training aspects like you did in Hana would be great. I feel that Hana and Kaisa had too much trouble to getting there (and that was great) and the other girls not so much. I get the idea of being "variety mindset" but I do believe these two things can be worked together.
Keep the great job, this game is on the road to be one of (or the one) best adult game(s).
