Ah yes, I tried running the game with Wine too and encountered this kind of crash, it seems some where resolved with the v09 build (is it the one you are running ?).
I'll also try to upload a Linux build later so you don't have to use Wine :)
It said I didn't had SFML libraries. I downloaded it and it ran, finally till the end without any crashes! So basically I didn't play through the whole part where you used the moon mechanic to its fullest. The whole game, basically. After finishing it, I cranked up some stars at your rating there, especially the innovation one. Very good level design! I think the crux of making new mechanics is having the level design to show it off and to teach it. I think you did a very good job there. You also made it non-linear at that second level, which I think is great for those games about learning on our own. The only complaints I would still have are with the camera and jump, but I'm sure it's mostly because you're working on a game jam's tight schedule. There's definitely a lot to explore with this concept. Great job, really!
Yep, I second this. When running ./Moonshot on Arch Linux I get:
./Moonshot: error while loading shared libraries: libsfml-graphics.so.2.5: cannot open shared object file: No such file or directory
I installed the sfml package and the game starts fine, works perfectly now! I wonder if you could bundle the so file with the game.
