This game was made in 2 hours. I'm leaving early Saturday morning and will be gone all weekend, but just had to make something for LudumDare.
Everything is created randomly, from the stalactites to the falling rocks & lava bursts, to even the animation order of the lava to give it a nice fluid look, that's different each time you load the level.
The game gets harder, spawning more objects, as your score increases. At 3000+ it's extremely crazy, being nearly impossible to survive long, but the spawn rate stops increasing at 3000.
Controls: Space - Start game Esc - Quit game Arrow Keys - Move
Estimated Sys. Requirements: Windows 2000+ 128mb ram 4mb video memory 400mhz CPU
Goal of the game: To survive as long as possible. Why are you traveling through a cavern of lava? No one knows. Just live man, LIVE!
