Rozière
In Rozière the player flies a balloon in a cave in a quest to explore it and then get out. Gas is very limited, so he must take advantage of special spots to heat and cool down his balloon (so gaining and losing altitude) without using gas. There's also gas springs in which he can recharge his gas supplies, but they're very sparse.
Like all spare-time project, Rozière may never see the light of day, but who knows...
My role: It is a solo project. I will only outsource the music to a friend, when I'll need it.
