I like the idea and the gameplay in the fundamental level. It's fun to free people from the enemy ships and upgrade your own ship. After figuring out what to do and getting over the controls, I found it quite a bit of to play this.
My two qualms are indeed the controls and the enemy ships being hard to chase due to them being so fast. Being able to play with keyboard or gamepad only would have been great instead of having to click the icons on the screen. Artificially making the enemy ships slower than the player's ship would have been nice too.
But, well, I know fully well how hard it is to make 3D games, nevermind in two weeks, so in that respect this is quite a good game. Add a fancy water shader, character animations, some piratey music and... Yeah, doing all that solo in such a short time is a really, really tall order, so what you have done is already a huge a achievement!
