You are offering your token to be sold, some of them will be used for operating cost, some will be used to develop the game further. If I may give another word to describe the current situation: you developed an MVP, and then opening yourself for funding, in form of token sale, in order to develop further and to cover the operating cost --and to compensate the dev team.
Yes, you're right.
But this is not a "asking for financing", we will start our project on self-financing. Tokens are important to us as game assets, which are more under the control of the player than non-tokenized game assets.
Of course, if someone supports us, it will help us, if not, we will handle the development on our own.
