The UI blends into the entire thing, it's nigh unreadable what is happening. There are good shortcuts, for slow stop or next wave that are clearly marked. And turrets aren't well differentiated in terms of how they affect specific enemies, at no point does it feel like new turrets are needed other than when a boss shows up specifically with an ability that current turrets don't handle. Art and UI definitely feel like slop, please add some contrats to the ui and not just colors.
Audio is pretty useless feels like I am playing with pew pew guns rather than big turrets also, visual cues for enemies is hard to parse and the entire game world is very noisy because the art direction is slop.
Only good part is that there is some replayability so you can try combinations but that does feel like a quirk of the genre rather than something that was built specifically for this game.
