If you can deliver on those promises, then consider me interested. Is there any way to get a developer forum here before the game launches? That'd give it a lot more visibility (and some competition for Harem Heroes).

I'll agree with other posters in that minimal time investment in our part is ideal. I dropped Phantasma (another match3 game on Nutaku) because each mission could take me 5-10 min to complete and I had to be actively invested in it the whole time. The writing and art was kind of trash too, but I was willing to wait to see if they improved.

I'm interested in your 'no gacha' claim. What's your alternative way to obtain units? The only other games I can think of without gacha are the clicker games.
