Very clean and polished. Great ui and feel, having both hotkeys and thorough mouse controls is somewhat rare among jam submissions and makes for a great experience here. A good amount of mechanical depth, with lots of room to expand. I found it a bit hard to reason about how well I was doing (as in, how optimal is my build?) but it is very satisfying and relaxing regardless. Got a little confused by the cooldowns... seems like when something is hit twice quickly, it can take longer to re-stock? Not quite sure, I just noticed that when you flank a blue with two reds, sometimes the first red and the blue trigger, but then the second red doesn't, even though the distance is the same. Really nice music. I liked how wild the upgrades get, last blue upgrade is wild :).
