good game
Best idle game i've ever played. Min-Maxing is awesome!
For what it is. Its okay. The math doesn't add up tho. ill add 100s% more to say damage and yet cant get any further. rn its 2x damage event. ok so why cant i progress? 2x thousands should mean i go further. but i cant. i still cant even get to 500 to unlock new heroes. So, while i put a thumbs up I honestly don't think its worth much time sink.
So, this is Idle Monster TD under a new name. According to Steam, I played the previous game for 2,500 hours. I gave that one a negative review because there was no way to hard reset and start over from scratch. Probably this one will have the same limitation, but right now I'm happy because I can start fresh. If micro-transactions bother you, you won't like this one. Personally, I don't have any problem ignoring those, which makes this game free to play, and I like free to play a lot. There are many upgrade paths and synergies to tinker with. The pace is fast. The grind is real. And this is one of those games that you can never finish, because there are always more levels to beat.
Jo is gut...
