It's ok, it's not a bad game and it starts interesting and it has good ideas, but it's A LOT of grind, nodebuster-like tree, small upgrades to atack and defense, very repetitive levels, it can't even go idle, you have to actively play them and aim at the trees and enemies... It's not my cup of tea, it's very repetitive and grindy but I'm sure some people will like this.
