Done :) I've uploaded the Linux build, let me know if there is anything wrong with it and I'll try to fix it !
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.
