This was surprisingly fun! Solid idea, well executed.
The level select was neat, too!
If I had one suggestion it'd be some kind of indicator as to where to the planet was since it's easy to lose track of once you go hunting in space. 😅
Unfortunately I bugged out around level 3 or 4 (whatever level had the distress signal ship you had to tow back), whenever I towed back to the planet it just restarted the level and there was weird overlapping with the UI messages so I couldn't finish the game in the end...
I'm also not really sure what it has to do with giving... I guess you're sorta giving the planets the thing to save them?
Fun game overall though!
