This is a neat game with a surprising amount of content. I didn't quite 100% it after buying everything because grinding until I randomly upgrade and see all the monsters was a bit too much...
But the main game is solid. There's a lot of nice art (Even if it is AI that doesn't bother me) and the upgrades feel like they come pretty quickly once you get into a rhythm. There is surprisingly some strategy to be found here at certain points but you don't have to engage with it much if at all. Highly recommend for BE enjoyers.
