\"\"<\/a><\/p>\n

Never-ending perlin caves to explore!<\/p>\n

Current features:<\/strong>
\n– Unlimited cave flying
\n– Plasma(?) cannon
\n– Moving around with keys (wasd\/arrow keys)
\n– Shooting with mousebutton
\n– 1 stone material
\n– added: light source, shooting sound, block destruction, basic collision detection for movement (not for player destruction yet)<\/p>\n

I’m thinking something like this, maybe another version with the cave in 2.5D and view from side:
