Thanks for your feedback Kaenkitanov!
You're absolutely right. We wanted to polish the core mechanic (the magnetic grappling hook) and the global experience before adding our other designed gameplay elements but we took to much time to polish everything (the sounds, Fx, art, level design) and we only found a good way for every of us to work simultaneously on our respective task too late. It was our main learning from this jam, the first we made together.
But still, I'm happy with the final result even if much of my work (as the game designer) is missing and the balancing completely messed up because of some bugs. We'll take time to fix it. And it's not the programmer fault, it's a shared responsibility ^^
Cheers
