Really addicting. Reminds me of Steven Universe, but I'm not gonna go too much into detail. Anyways, I've been playing this for DAYS now (yes, it's that addicting!), and I have noticed some things. It's another tower defense game, this time with gems. Tower defense is a really common game type; it's become a cliche to me. Other than that, great job!
EthanWallee70, it's rated teen because of the blood the monsters leave behind.
