I like the idea behind this one but it definitely needs a little more polish. Making it so the islands deal damage was a nice, realistic touch but I agree that colliders would have been a good idea as well to prevent people from going through them. It would be nice to have the game end after reaching 0 health but I assume time was a big factor it that. If you plan to continue the game after the jam, I think it can be a fun little concept with a bit more time into it.

Sorry, but it was bad. You going thought islands without any collision, crew bar is doing nothing(Or i wasn't able to find anything to do with it), ship is just moving without rotation and sometimes rotates after you lose health and change controls.

I guess reason for it is time, so beside all that i mentions higher, game fits the theme and have some gameplay concept behind it, so if you're planning expand game after the jam - good luck!
