I like this game, it's not quite the copy pasted idle game like most others. Unfortunately it's very short in terms of progression to max level. I think it's absurd to have things like $60 packs for an obviously unfinished game. I liked the direction I was progressing in, spent about $10, to find out there is no progression in research. Worker upgrade of tiers also costs a lot, by the time I finished the game, I had upgraded about 5 workers. 4.5 stars was obviously paid for
