I really like the presentation, very clean. There were some issues with weird shadows appearing on the sand (I think?) but overall very nice.
In terms of feedback, a few things stood out to me. One was that the camera felt too sensitive, or the ship was too big on the screen, or possibly a combination of both? Either way, I often had difficulty getting my bearings. It also took me awhile to figure out that the railgun's on a cooldown and I wasn't sure if I was firing it or not - even when I figured out it was on a cooldown, I wasn't sure if I needed to face the enemy directly or fire from the side pirate style.
Pretty cool concept and I'm looking forward to playing the final version to see where this goes!
