I think the gameplay loop is shallow and the base building is novel but rudimentary. Fundamentally it's a game about how well you manage the wait times but there's so many small annoying things relating to that. Like how the map is excessively large yet the game doesn't have ways to speed up navigation nor a map to quickly jump to any area on the map. Considering you're so confined to one area, what's the point? It's also not too hard to snowball yourself to victory unless you get rng screwed.
