I really want to like this game. I do. But after playing since its release, it’s unbelievably apparent that it’s p2w. And that’s just unforgivable. Unless you get lucky on a draw, any kind of progression is insanely slow. Like we’re talking 6-8 months of playing daily to get a 3 Star to a 5 Star, when people who pay money can just get a 5* right off the bat. Progression is painful, and it’s my only issue. And upgrading monsters is all RNG based on top of everything. Spend and month trying to get a monster to its next level? Sorry, now you’re going to have to spend another month and insane amounts of gold breeding it to randomly get a chance to level it up. I want to like this game, I really do. But the progression mechanics are terrible. Not worth playing at all. Gave it an extra star just for design, because I do love that aspect

Improvements recommended

I highly recommend global catches up to jp via units and events. That’ll make this game more fun!
I also do recommend doing more advertising. I played the Japanese version last year and I had NO idea an English version came out recently... So maybe some more advertising to build the community (along with events and new stuff, of course)
Overall, a pretty decent game

Great game!

Cosmic Eggs doesn’t fail when advertising! You really get addicted to this game since you can breed new hybrids and get friends to support you in your battles.
