Cool game. I can't gow down with the S key but I can with the down arrow, I don't know if it's a bug or it's intended. I died while rescuing a person and when I revived I couldn't move :S. I like the retro style of the game and the music.
Thanks for the feedback. I completely forgot to map the 'S' key to also function like the down arrow. I'll get that fixed. As for dying while rescuing a miner and then not being able to move after re-spawning, I haven't encountered that. I'll try to replicate it,
