Very good game, at the moment of writing its my favorite game!
I like the weapon variety and build posibilities. the 2 maps that are available at the time of writing seem polished and are fun to play on.
the only thing i would love to see it a system that makes upgrading turrets and gems easier. maybe a upgrade button and that automatically uses the resources needed for that item? and also a button to remove gems from weapons and turrets would be nice. looking for the right items is becoming a struggle as my inventory get bigger.
conclusion, 8/10, would recommend!
