Good game.
Gameplay is nice, but it's a bit hard to jump precisely.
Also some music will be nice.
But in overall i like idea of rising lava in platformer.
Good job!
The music for a solo dev like me it's a nightmare. The sfx is the minimum. BTW thanks for playing and for the feedback!
You can find music on the internet that fits your game (and add credits of music author if music license require this)
