Might be a bug, or might be something I misunderstood, but I wasn't able to repair the ship several times after collecting more than enough resources of all types. If I had to guess, it has something to do with storing the items after arriving back at the ship, because the first time I played, I didn't return until the backpack was full, and I could repair it that one time. Since I knew there was a capacity limitation, I started returning often to unload, and I was never able to repair then or in my subsequent playthroughs.

I actually didn't realize that the ship was taking damage over time, so I didn't repair on purpose since I was thinking of saving up for a hook/backpack upgrade instead. Then I got the in game warning, but I still could not repair unfortunately.

I really like the game idea though, and other than the situation I encountered, I think the presentation is pretty good. Similar to ocaviobia's comment, I'd suggest making it clearer if the hook should reach a target or not and/or make the upgrade for it cheaper so it can be acquired more quickly. Grouping the craters at distances that are easy to tell at a glance if the player can reach would help with route planning so you don't have to grapple to a location only to realize you are at a dead end and have to go back

Cool concept and good execution! My only complaints were that the aim assist on mouse felt too rigid and the lack of a visual indicator if my hook can reach a helipad or not. Nice game nonetheless, congrats!
