@eli-delventhal terribly sorry about the mouse sensitivity - I have no idea why the web player is so much more sensitive than any other build. You can get by with a mouse but a trackpad must have been torture. I've added the controls to the game's description, so hopefully that will help. There are 16 locations where holes can appear in the ship, and every room has 1-2 locations for holes to appear (with the large hall leading to the bridge being the exception having 3. The 3 bunk closets can *not* have holes in them because that would be horrible.
As for patching holes: The small ones are small enough that some duct tape can cover that up, which it turns out you always have on you. The large holes require a patch though, and there are two rooms with stacks of patches. These are definitely areas where being able to do playtesting mid-jam would yield tremendous dividends.
