I really liked your game. I hate you for getting a Steam Frame before me (waitlisted) but I am really happy to see it being used for game design already. My only critique is I would like a toggle to hold for the controller instead of just holding down the grab button but that is because I am on a Odyssey controller so I don't have finger tracking.
The wave physics is spot on and I love how the speedboat jumps over its own wake. I spent a ton of time in the sandbox mode at the end just having it doing figure eights around all the other stuff. Great job.
