Well... if it is really "complete" without the final level among other things that were promised but were not fulfilled due to lack of inspiration or personal problems. Better not to complain and be satisfied with the result even though there are many things to be added.
So guys, creating a game is not easy, it requires a lot of time and as an example we have Project X from its first versions, many years of development to be unfinished, if you have the necessary resources, good morale among your colleagues of the game project and promise to finish it.
Do it, there are already many games made by a small group of people that are quite interesting and fun even by a single person, but some games remain unfinished.
