Extremely well executed.
Art was great, sound design was solid enough to support everything else. Very cohesive and felt complete (except for the obvious placeholders like the truck explosion, which was hilarious). I think the minigame worked well as a fairly chill experience before things kicked off.
Best entry I've seen so far by a mile.
My critiques:
I'm playing on a trackpad, so I found the aiming controls to be a little annoying during the shooting minigame. The click targets for the buttons seemed slightly messed up. I do think the gameplay/upgrades centered more around the storm than the calm before the storm.
