A lot of work was probably put into the game, but unfortunately almost nothing works. It feels like a very early beta version.
e.g. "0/2 units" are displayed at the bottom left, but although there are 2 units, the left/right arrows don't work to switch between units. OK: Once in a while the arrows work, but only for one run.
Or the tutorial: hardly any of the actions described work. Either you have to call up a city menu, which you can't find, or you are supposed to choose "found a city" and you can actually find this command! - but of course you can't activate it.
But to sum up: even the first 3 minutes are very disappointing...
