A very good first game in 3D, some nice level design and decent controls. There's some interesting mechanics here and a nice overall design. Though I do have to say the hitbox of the player seemed to be a bit off leading to some clipping while trying to jump certain areas, mainly small ledges when I was too close. Once I figured it out though it wasn't too much of an issue, just led to some hilarious deaths.
I do have to say the title screen and the overall lava... shader? I assume, was quite interesting, especially the little easter egg floating around on the vast magma abyss.
Overall a great first 3D game, and a great overall jam game!!
